Understanding Waves and Their Properties

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another, caused by a change in its speed.

Front

What wave property is measured in Hertz (Hz)?

Back

Frequency is measured in Hertz (Hz), which indicates the number of waves that pass a point in one second.

Front

What is the Doppler Effect?

Back

The Doppler Effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Front

What happens during superposition of waves?

Back

During superposition, two or more waves combine to form a new wave pattern, which can result in constructive or destructive interference.

Front

Which type of wave has the highest frequency: Radio waves, Visible light, Ultraviolet, or X-rays?

Back

X-rays have the highest frequency among these options.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles and the spreading out of waves when they pass through narrow openings.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is amplitude in the context of waves?

Back

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

Front

How can the Doppler Effect be used in astronomy?

Back

In astronomy, the Doppler Effect can be used to determine the movement of stars by observing changes in the frequency of light they emit.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet in phase, resulting in a wave of greater amplitude.
