Sound and Light

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium. In sound waves, it relates to the loudness, while in light waves, it relates to brightness.

Front

What happens to the brightness of light when the amplitude is increased?

Back

The brightness of light increases when the amplitude is increased.

Front

What color does a green filter allow to pass through?

Back

A green filter allows green light to pass through and absorbs all other wavelengths.

Front

Which color of light has the shortest wavelength?

Back

Violet light has the shortest wavelength among visible colors.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed.

Front

What is reflection in terms of light?

Back

Reflection is the bouncing back of light when it hits a surface.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is the definition of diffraction?

Back

Diffraction is the spreading of waves around obstacles and openings.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.
