Waves

Front

What is the definition of amplitude in a wave?

Back

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

Front

What phenomenon occurs when a wave changes direction as it passes from one medium to another?

Back

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

Front

What is the term for the lowest point on a wave?

Back

The lowest point on a wave is called the trough.

Front

How is wavelength defined in the context of waves?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as from crest to crest or trough to trough.

Front

What happens to the wavelength of a wave when its frequency increases?

Back

When the frequency of a wave increases, the wavelength decreases.

Front

What is the relationship between frequency and period in a wave?

Back

The frequency is the number of cycles per second, while the period is the time taken for one complete cycle; they are inversely related.

Front

What is the term for the highest point on a wave?

Back

The highest point on a wave is called the crest.

Front

What is the formula for calculating wave speed?

Back

Wave speed can be calculated using the formula: Wave Speed = Frequency x Wavelength.

Front

What is the significance of wave frequency in sound waves?

Back

In sound waves, frequency determines the pitch of the sound; higher frequencies correspond to higher pitches.

Front

What is constructive interference in wave behavior?

Back

Constructive interference occurs when two waves meet and combine to form a wave with a larger amplitude.
