To change the frequency would mean to have more or less cycles per second. This would require manipulating time, which isn't the case here.

What is the name for a change in the direction of a wave when it passes one medium into another?

refraction


What is a change in direction of a wave as it passes from one medium to another?

Refraction is the change in direction of a wave as it passes from one medium to another. This change occurs because the wave changes speed when it moves from one medium to another, causing it to bend.


How are sound waves are affected by their frequency and the medium through which the sound wave passes?

The wavelength is equal to the local velocity of sound divided by the frequency, As with light, there can be refraction when sound passes from one medium to another with a different sound velocity.


When a wave passes from a less dense medium to a more dense medium what might change?

When a wave passes from a less dense medium to a more dense medium, its speed decreases while its frequency remains unchanged. Additionally, the wave may also experience refraction, causing it to change direction.


What will be change in a wavelength and frequency when wave refracted?

When a wave refracts as it moves from one medium to another, its wavelength typically changes while its frequency remains constant. The change in wavelength is due to the change in speed of the wave in the new medium, as dictated by Snell's Law. The frequency remains constant because it is a characteristic of the source of the wave and does not change as the wave passes through different mediums.


Does the frequency of a whales sound made underwater changes after being heard in air?

When a sound passes from one medium to another of different [non-zero] density, its speed and wavelength change, but its frequency doesn't. It doesn't matter what either medium is, or what source produced the sound.

When a wave passes froma less dense medium to a more dense medium the may change?

When a wave passes from a less dense medium to a more dense medium, it generally slows down and changes direction. This change in speed and direction is called refraction. The wave may also experience a change in wavelength and frequency.


What light does as it passes from one medium to another?

Light changes speed and direction as it passes from one medium to another due to the change in density between the two media. This change in speed and direction is known as refraction.


The bending of a wave as it passes from a medium to another is called what?

The bending of a wave as it passes from one medium to another is called refraction. This phenomenon occurs due to a change in the wave's speed as it enters a different medium with a different density.


When a light wave travels form air into water the quantity that remains unchanged it its speed amplitude wavelength or frequency?

When a light wave travels from air into water, its frequency remains unchanged. This is due to the fact that the frequency of a wave is determined by the source that creates it, and does not change when it passes from one medium to another.


What happens to the frequency and speed of an electromagnetic wave as it passes from air into glass?

As the electromagnetic wave passes from air into glass, the frequency remains the same, but the speed decreases. This is due to the change in the medium's refractive index, which causes the wave to slow down as it travels through the denser medium of glass.
