Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

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.

Front

What is frequency in the context of waves?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

As the wavelength increases, the frequency decreases, and vice versa.

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 an electromagnetic (EM) wave?

Back

An EM wave is a wave that can travel through the vacuum of space and consists of oscillating electric and magnetic fields.

Front

What are the different types of electromagnetic waves?

Back

The types of EM waves include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is reflection in terms of waves?

Back

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