Waves and Light

Front

What affects the amplitude of a sound wave?

Back

The amount of energy that is put into a wave determines its amplitude.

Front

In which medium does light have the lowest velocity?

Back

Diamond (n=2.45) has the lowest velocity for light.

Front

What is the angle of reflection?

Back

The angle of reflection is equal to the angle of incidence.

Front

What is the vertical height of a transverse wave called?

Back

Amplitude.

Front

What is the law of reflection?

Back

The angle of incidence is equal to the angle of reflection.

Front

What is wavelength?

Back

The distance between two consecutive crests or troughs in a wave.

Front

What is frequency?

Back

The number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is wave speed?

Back

The speed at which a wave travels through a medium, calculated as wave speed = frequency × wavelength.

Front

What is refraction?

Back

The bending of light as it passes from one medium to another due to a change in speed.

Front

What is total internal reflection?

Back

The complete reflection of light back into a medium when it hits the boundary at an angle greater than the critical angle.
