BELLRINGER#3 Waves & Behavior

Front

What is diffraction in the context of waves?

Back

Diffraction is the bending of waves around obstacles and openings, which causes waves to spread out after passing through narrow openings.

Front

What does a wave transfer?

Back

A wave transfers energy.

Front

How do you calculate the frequency of a wave?

Back

Frequency (f) can be calculated using the formula f = v / λ, where v is the speed of the wave and λ is the wavelength.

Front

If a wave has a wavelength of 5 m and a speed of 240 m/s, what is its frequency?

Back

The frequency of the wave is 48 Hz.

Front

What happens to the amplitude of a wave when more energy is added?

Back

The amplitude of the wave increases.

Front

What is required for a mechanical wave to propagate?

Back

A mechanical wave requires a medium (solid, liquid, or gas) to travel through.

Front

What is the relationship between wavelength and frequency in waves?

Back

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

Front

What is the definition of amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (which require a medium) and electromagnetic waves (which do not require a medium).

Front

What is the speed of a wave?

Back

The speed of a wave is the distance traveled by a point on the wave in a given amount of time, often calculated as speed = wavelength × frequency.
