Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its wavelength, frequency, and amplitude.

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 wavelength?

Back

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

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.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.

Front

What is refraction?

Back

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

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface that it cannot pass through.

Front

What are the primary colors of light?

Back

The primary colors of light are red, green, and blue. These colors can be combined to create other colors.

Front

What is the role of cones in the eye?

Back

Cones are photoreceptor cells in the retina that detect color and are responsible for color vision.

Front

What is the difference between gamma rays and x-rays?

Back

Gamma rays have a higher frequency and energy than x-rays and are often used in cancer treatment.
