Physics Waves Review

Front

What is diffraction?

Back

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

Front

What does the frequency of sound waves determine?

Back

The frequency of sound waves determines the pitch of the sound.

Front

What type of lens is represented by a concave shape?

Back

A concave lens is a type of lens that diverges light rays.

Front

What does wavelength represent in a wave?

Back

Wavelength is the distance between successive crests or troughs in a wave.

Front

Which wave has the longest wavelength?

Back

Wave R has the longest wavelength.

Front

What is the principle of superposition in wave interference?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves.

Front

What is the difference between compression and rarefaction in sound waves?

Back

Compression is the region in a longitudinal wave where particles are closest together, while rarefaction is where they are furthest apart.

Front

What is the relationship between amplitude and loudness?

Back

The amplitude of a sound wave is directly related to its loudness; higher amplitude means louder sound.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

What is the formula for calculating wave speed?

Back

Wave speed = frequency × wavelength.
