When light travels from one medium to another with a different index of refraction, how is the light's frequency and wavelength

lbvjy [14]

Answer:

The frequency does not change, but the wavelength does

Explanation:

Here are the options

A. When a light wave travels from a medium with a lower index of refraction to a medium with a higher index of refraction, the frequency changes and the wavelength does not.

B. The frequency does change, but the wavelength remains unchanged.

C. Both the frequency and wavelength change.

D. When a light wave travels from a medium with a lower index of refraction to a medium with a higher index of refraction, neither the wavelength nor the frequency changes.

E. The frequency does not change, but its wavelength does.

When light goes through one medium to the next, the frequency doesn't really change seeing as frequency is dependent on wavelength and light wave velocity. And when the wavelength shifts from one medium to the next.

$n= \frac{C}{V} \ and\ \frac{\lambda_o}{\lambda_m}$

where $\lambda_o$ indicates wavelength in vacuum

$\lambda_m$ indicates wavelength in medium

n indicates refractive index

v indicates velocity of light wave

c indicates velocity of light

And wavelength is medium-dependent. Frequency Here = v $\lambda$ and shift in wavelength and velocity, not shifts in overall frequency.

Therefore the correct option is E

Suppose your hair grows at the rate of 1/55 inch per day. Find the rate at which it grows in nanometers per second. Because the

qwelly [4]

Answer:5.35nm

Explanation:

Consider that 1 inch is = 0.0254m

we have,

1m= 1x10^9 nm

While:

0.0254m = 2.54x10^7nm

1/55 (2.54x10^7) = 4.6181 x 10^5nm

1 day= 24 hrs

= (24x60) when calculating in min

= (24x60x60) calculating in seconds we have:

= 8.64x10⁴sec

In 8.64x10^4 seconds, the hair grows by 4.6181 x 10^5nm

Therefore, the amount by which the hair grows in 1 second will be;

= (4.6181 x 10^5)/(8.64x10^4)

= 5.35nm

The rate of growth will be 5.35nm

Which material is more closely related to the styrofoam? a. heat exchanger b. diffuser c. insulator d. electrical conductor

nirvana33 [79]

The material that is more closely related to the Styrofoam insulator.

Styrofoam is the term that is used for polystyrene foam in a trademark form. It is a petroleum-based plastic.

Keeping something warm includes the stopping of the transfer of heat from one object to another. This is how insulation works.

Styrofoam is an insulator, which means it'll help keep the heat from the environment out of your cooler. However, you'll still need cooling agents (like ice packs) to make the cooler cold in the first place.

Styrofoam is usually made mostly of air, which means it is a poor conductor of heat, but an excellent convector. It traps the air in small pockets, which blocks the flow of heat energy. This reduces both conduction and convection and makes Styrofoam a good insulator.
