ADP10 - Q2 Science Exam Review

Front

What happens to wave energy when amplitude increases?

Back

Greater amplitude → more energy; energy ∝ amplitude².

Front

What happens to wavelength if frequency doubles?

Back

Wavelength is cut in half.

Front

How do particles move in transverse vs. longitudinal waves?

Back

Transverse = perpendicular; Longitudinal = parallel.

Front

What determines the loudness of a sound?

Back

Amplitude.

Front

What determines the pitch of a sound?

Back

Frequency; higher frequency = higher pitch.

Front

What is resonance?

Back

When one object vibrates due to matching frequency from another.

Front

Why does sound travel faster in solids?

Back

Particles are closer together.

Front

What type of wave is light and does it need a medium?

Back

Light is a transverse electromagnetic wave; it does not need a medium.

Front

Which EM wave has the highest energy and which has the lowest?

Back

Gamma rays = highest; Radio waves = lowest.

Front

Why does black get hotter than white?

Back

Black absorbs more light; white reflects.
