Wave Transmissions Review Sheet

Front

What happens to the speed of light when it goes from a gas to a solid?

Back

The speed of light decreases when it goes from a gas to a solid due to the increased density of the solid medium.

Front

What does a diffracted sound wave do?

Back

A diffracted sound wave changes direction and spreads out as it passes through an opening or around an obstacle.

Front

List the states of matter from fastest to slowest for sound movement.

Back

The states of matter from fastest to slowest for sound movement are Solid, Liquid, Gas. Sound travels fastest in solids because the particles are closer together.

Front

What represents a loud sound wave?

Back

A loud sound wave is represented by a wave with high amplitude.

Front

What is diffraction?

Back

Diffraction is the bending and spreading of waves when they encounter an obstacle or pass through an opening.

Front

How does sound travel in different states of matter?

Back

Sound travels fastest in solids, slower in liquids, and slowest in gases due to the arrangement and density of particles.

Front

What is amplitude in sound waves?

Back

Amplitude is the height of the wave, which determines the loudness of the sound; higher amplitude means louder sound.

Front

What is frequency in sound waves?

Back

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

Front

What happens to sound waves in a vacuum?

Back

Sound waves cannot travel in a vacuum because there are no particles to transmit the sound.

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.
