Light Waves Ch. 1 and Ch.2 AMplify Enns

Front

What are light waves?

Back

Light waves are electromagnetic waves that carry energy from one place to another, even through empty space.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks of a wave, which determines the type of light.

Front

What is amplitude?

Back

Amplitude is the height of a wave from its rest position, which affects the brightness of the light.

Front

How does light interact with materials?

Back

Different types of light can change a material in different ways, such as reflection, absorption, or transmission.

Front

What is visible light?

Back

Visible light is the part of the electromagnetic spectrum that can be seen by the human eye, making up a small part of the entire spectrum.

Front

Can light carry energy?

Back

Yes, light carries energy from one place to another, which can affect materials it interacts with.

Front

What happens when light hits a surface?

Back

When light hits a surface, it can be reflected, absorbed, or transmitted depending on the properties of the material.

Front

What is the relationship between wavelength and color?

Back

Different wavelengths of light correspond to different colors; shorter wavelengths appear blue, while longer wavelengths appear red.

Front

What is a laser?

Back

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
