Next Question

The distance from one point on a wave to the exact same spot on the next wave is called the ________.

The distance from one point on a wave to the exact same spot on the next wave is called the wavelength.

Next Question

As the wavelength increases the frequency _______. on the next wave is called the wavelength.

As the wavelength increases the frequency decreases. on the next wave is called the wavelength.

Next Question

Next Question

When you see your image in a mirror or the water of a lake, you are seeing waves being sent back to you as a ______.

When you see your image in a mirror or the water of a lake, you are seeing waves being sent back to you as a reflection.

Next Question

_______ is the bending of light rays as they move from one kind of medium to another (air to water).

Refraction is the bending of light rays as they move from one kind of medium to another (air to water).

Next Question

The bending of waves around an obstacle is called ________. one kind of medium to another (air to water).

Next Question

Next Question

The Doppler Effect is the change in wavelength by the movement of the wave source.

A wave has a wavelength of 4 cm. Twenty waves pass a certain point in 5 seconds. What is the frequency?

Frequency = waves/time certain point in 5 seconds. What is the frequency?

Frequency = 20/5

Frequency = 4 waves/sec.
