Why doesn't an electromagnetic wave move as fast through a solid as it would a gas

Because in a solid the atoms are a lot closer together, and depending on the size, a lot more of them. In gas, there is in fact more atoms, but they are not as close together, making it easier of the waves to travel along.

A laser produces 20.0 mW of red light. In 1 hour, the laser emits 2.29 X 10^20 photons. What is the wavelength of the laser?

Using Planck's equation,

E = nhc / λ

Also, Power = Energy / time
E = 20 x 10⁻³ x 60 x 60
E = 108 J

108 = (2.29 x 10²⁰ x 6.63 x 10⁻³⁴ x 3 x 10⁸) / λ
λ = 4.22 x 10⁻⁷ m

A sled and rider, gliding over horizontal, frictionless ice at 4.7 m/s , have a combined mass of 80 kg . The sled then slides over a rough spot in the ice, slowing down to 3.4 m/s . What impulse was delivered to the sled by the friction force from the rough spot? Express your answer to two significant figures and include the appropriate units.

Impulse is the change in momentum.
All we need is the momentum before and after.

Momentum  =  (mass) x (speed)

Before:        =  (80 kg) x (4.7 m/s)  =  376 kg-m/s

After:           =  (80 kg) x (3.4 m/s)  =  272 kg-m/s

Change in momentum  =  (376 - 272) =  104 kg-m/s


Notice that when you work with impulse, you're USUALLY calculating

                           (force) x (time).

The force is in Newtons, and the time is in seconds,
so the impulse is usually in units of

                             Newton-seconds .

So how can I say that impulse and change of momentum are
the same thing ?  Am I trying to pull a fast one on you ?

Remember that    1 Newton is  1 kg-m/s²

So                       (force) x (time) 

                     =  (Newton) x (second) 

                     =  (kg-m/s²) x (second)  =  kg-m/s .

and  Momentum = (mass) x (speed)  =  (kg) x (m/s)

The units of impulse are the same as the units of momentum !

So when you give an object some impulse, you give it exactly
that much momentum.

All waves consist of a continuous series of _____. pulses circles compressions rarefactions

Answer: The correct answer is pulses.

Explanation:

Wave is a disturbance which carries energy from one particle to another. Wave is a continuous disturbance.

Pulse is a single disturbance. It travels through one point to another.

Sound wave consists of rarefaction and compression. It need medium to travel.

In the circular wave, the particles move both parallel and perpendicular to the motion of the wave.

Therefore, all waves consist of a continuous series of the pulses.

Microwave ovens emit microwave energy with a wavelength of 12.5 cm. What is the energy of exactly one photon of this microwave radiation? I'm on sapling and I did it couple times, but I kept getting it wrong!!! I followed all the notes I have from lecture, can someone please help thank you

The energy of exactly one photon of this microwave radiation is \boxed{1.584\times10^{-24}\text{ J}}.

Further Explanation:

Planck’s equation used to solve this question. In the Planck’s equation, the energy of a photon is directly related to the frequency of a photon and inversely related to the wavelength of a photon.

By using Planck’s equation the energy of the one photon can be determined.

The term “Electromagnetic wave radiation energy” was first introduced by the scientist Max Planck.

The light can travel very fast as in the no other thing can travel as faster as light and it’s measures value is approximate 3.0\times{10^8}{\text{ m/s}} in vacuum.

The wavelength is the defined as the distance between two consecutive positive peak pointornegative peak point of the wave.

Given:

The wavelength of the energy is 12.5\text{ m}.

Concept:

The expression for the energy of photon is:

\boxed{E=\dfrac{{h\cdot c}}{\lambda}}

Here, E is the energy of photon, h is the Plank constant, c is the speed of the light and \lambda is the wavelength of the photon.

The value of the Plank constant is 6.6\times{10^{-34}}{\text{ J}\cdot\text{s}}.

The value of the speed of the light is 3.0\times{10^8}\text{ m/s}.

Substitute 6.6\times{10^{-34}}{\text{ J}\cdot\text{s}} for h, 3.0\times{10^8}\text{ m/s} for c and 12.5\text{ cm} for \lambda in the above equation.

\begin{aligned}E&=\dfrac{{\left( {6.6 \times {{10}^{ - 34}}{\text{ Js}}} \right) \cdot \left( {3.0 \times {{10}^8}{\text{ m/s}}} \right)}}{{12.5{\text{ cm}}}}\\&=\dfrac{{\left( {6.6 \times {{10}^{ - 34}}{\text{ Js}}} \right) \cdot \left( {3.0 \times {{10}^8}{\text{ m/s}}} \right)}}{{12.5 \times {{10}^{ - 3}}{\text{ m}}}}\\&=1.584 \times {10^{ - 24}}{\text{ J}}\\\end{aligned}

Therefore, the energy of exactly one photon of this microwave radiation is \boxed{1.584 \times {10^{ - 24}}{\text{ J}}}

Calculate the wavelength of light emitted when each of the following n=5 n=3

When it transmits from n=5 to n=3, 
∧ = Rh [ni - nf]
∧ = Rh [1/3-1/5]
∧ = Rh 2/15

So, your final answer is Rh * 2/15
Where, Rh = Rydberg's constant

Your boss asks you to adjust the temperature so that a sound wave travels more quickly through the air you increase the temperature from 30 c to 36 c what's the velocity of the sound wave at this new temperature

Answer:

initial speed of sound at 30 degree C

v_1 = 349.6 m/s

final speed of sound at 36 degree C

v_2 = 353.2 m/s

Explanation:

As we know that velocity of the sound in air is given by the formula as

v = 331.6 + 0.6 t

here we know that

t = temperature or air in degree celcius

so here at 30 degree celcius we can say that

v_1 = 331.6 + 0.6(30)

v_1 = 349.6 m/s

now at 36 degree C the speed of sound is given as

v_2 = 331.6 + 0.6(36)

v_2 = 353.2 m/s

Describe a compression and a rarefaction of a sound wave traveling through air.

Compression occurs when the emitter is moving towards the observer compressing the wavelengths. This increases the pitch and is the 1st half of the Doppler effect.

How does wave energy impact the erosion of a rock?

Whenever these waves reach the shoreline, these slow down.  The first parts of the shoreline that waves meet are the headlands. This is the part of the land that projects into the water. The slowing waves bend toward the headlands, which concentrates the waves' energy. A huge amount of energy is released when waves crash into headlands, causing the land to erode.

A widow's peak is a V-shaped area of the hairline in the center of the forehead. The allele for having a widow's peak is dominant to the allele for not having a widow's peak. If two parents do not have widow's peaks, what is the probability that their child will have a widow's peak? A. 75% B. 0% C. 25% D. 50%

Answer:

B.  

0%

Explanation:

A widow's peak is a V-shaped point in the hairline in the center of the forehead. Hair growth on the forehead is suppressed in a bilateral pair of periorbital fields. Without a widow's peak, these fields join in the middle of the forehead so as to give a hairline that runs straight across.
