What is a light wave?

Back

A light wave is a type of electromagnetic wave that is visible to the human eye, responsible for the sense of sight.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum extent of a wave's oscillation, measured from its rest position. It determines the wave's energy.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests (or troughs) of a wave, usually measured in meters.

Front

How does light from the sun affect materials?

Back

Light from the sun can transfer energy to materials, causing changes such as fading colors or drying substances.

Front

What is the difference between sunlight and light from a desk lamp?

Back

Sunlight contains a broader spectrum of light and more energy compared to the light from a typical desk lamp.

Front

What happens to a rug's color when exposed to sunlight over time?

Back

The rug absorbs energy from the sunlight, which can cause its color to fade.

Front

Can light change the physical properties of materials?

Back

Yes, light can change physical properties by transferring energy, which can lead to effects like fading or drying.

Front

What is the role of energy in light waves?

Back

Energy in light waves determines their intensity and can affect how they interact with materials.

Front

What is reflection in terms of light waves?

Back

Reflection is the bouncing back of light waves when they hit a surface, allowing us to see objects.

Front

What is transmission in light waves?

Back

Transmission is the passage of light through a material, which can affect how we perceive colors and brightness.
