Waves

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium.

Front

What is the amplitude of a wave?

Back

Amplitude is the measurement between the rest position and the highest or lowest point of a wave.

Front

What is a medium in the context of waves?

Back

A medium is a material through which a wave travels, such as air, water, or solid substances.

Front

What is the difference between longitudinal and transverse waves?

Back

Longitudinal waves have oscillations in the same direction as the wave travels, while transverse waves have oscillations perpendicular to the direction of wave travel.

Front

What is the wavelength of a wave?

Back

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

Front

What is frequency in relation to waves?

Back

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

Front

What is the speed of a wave?

Back

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

Front

What is reflection in terms of wave behavior?

Back

Reflection is the bouncing back of a wave when it hits a barrier or surface.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another due to a change in speed.

Front

What is diffraction?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles.
