What are the two main types of waves?

Back

Mechanical waves and electromagnetic waves.

Front

What is the wavelength of a wave?

Back

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

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 amplitude?

Back

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

What is the relationship between wavelength and energy in light waves?

Back

Shorter wavelengths correspond to higher energy, while longer wavelengths correspond to lower energy.

Front

What are rarefactions in sound waves?

Back

Rarefactions are areas of low pressure in a sound wave where particles are spread apart.

Front

How does sound travel through different materials?

Back

Sound travels fastest through solids because particles are closely packed, allowing sound waves to bounce off particles quickly.

What happens to light when it passes through a convex lens?

Back

Light rays converge to a point after passing through a convex lens, focusing the light.

What is refraction?

Back

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