6.P.1.2 Light Waves

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through space and do not require a medium. They include visible light, radio waves, X-rays, and more.

Front

Which color of light has the least amount of energy?

Back

Red light has the least amount of energy among visible colors.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, causing objects to appear broken or displaced.

Front

Which type of electromagnetic wave has the highest frequency?

Back

Gamma waves have the highest frequency among electromagnetic waves.

Front

How does light enable us to see objects?

Back

Light reflects off an object and then enters the eye, allowing us to see the object.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from red to violet.

Front

What is absorption in terms of light?

Back

Absorption is the process by which an object takes in light energy, preventing it from being reflected or transmitted.

Front

What is transmission in the context of light?

Back

Transmission is the passing of light through a medium without being absorbed.

Front

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.
