Waves

Front

What part of a sound wave measures LOUDness?

Back

Amplitude is the part of a sound wave that measures loudness.

Front

What happens to a light wave when it passes from air into glass?

Back

The light wave is refracted when it passes from air into glass.

Front

In which medium does sound travel fastest?

Back

Sound travels fastest in solids because the particles are closer together than in air.

Front

What occurs when a light ray hits the surface of a mirror?

Back

The light ray is reflected at an angle equal to the angle of incidence.

Front

Which travels faster: infrared or x-rays?

Back

X-rays travel faster than infrared.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave.

Front

What is frequency in the context of waves?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings.

Front

What is reflection in terms of light waves?

Back

Reflection is the bouncing back of light waves when they hit a surface.
