Sound and Light Waves Practice Flashcard

Front

What happens to a sound wave when it moves from a gas to a solid?

Back

It speeds up.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes at an angle from one medium to another.

Front

Why do waves refract?

Back

Waves refract because the speed of a wave changes as it moves from one medium to another.

Front

What causes the appearance of a broken stem in water?

Back

The appearance of a broken stem is caused by refraction.

Front

What color does an object appear if it absorbs all colors except yellow?

Back

The object appears yellow.

Front

How does the energy of electromagnetic waves relate to their frequency?

Back

Electromagnetic waves with higher frequencies have more energy than waves with lower frequencies.

Front

What is a medium in the context of sound waves?

Back

A medium is the substance through which sound waves travel, which can be a solid, liquid, or gas.

Front

What happens to the speed of sound when it travels through different media?

Back

The speed of sound changes depending on the medium; it generally speeds up when moving from gas to solid.

Front

What is the relationship between wavelength and frequency in waves?

Back

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

Front

What is reflection in terms of wave behavior?

Back

Reflection is the bouncing back of a wave when it hits a barrier.
