Light Waves- Assessment

Front

What is the effect of different types of light on materials?

Back

Different types of light can affect the same material or object in different ways. For example, radio waves can be transmitted through plant cells while visible light is absorbed.

Front

How do we perceive an object as being the color white?

Back

We perceive an object as being the color white when all colors of visible light are reflected off the object and then to our eye.

Front

What is produced by vibrating objects through air?

Back

Sound is produced by vibrating objects through air.

Front

What is the distance from one peak of a wave to the next called?

Back

The distance from one peak of a wave to the next is called the wavelength.

Front

Which type of signal is more reliable over long distances?

Back

Digital Signal is more reliable and accurate over long distances because it is a copy using numbers (1s and 0s) that is exactly the same every time.

Front

What is wavelength?

Back

Wavelength is the distance between one peak of a wave and the next peak.

Front

What is the difference between digital and analog signals?

Back

Digital signals use discrete values (1s and 0s) and are more reliable, while analog signals vary continuously and can pick up noise.

Front

What happens to light when it hits a black object?

Back

A black object absorbs all colors of visible light and reflects none, making it appear black.

Front

What is the role of visible light in photosynthesis?

Back

Visible light is absorbed by chlorophyll in plants, which is essential for photosynthesis.

Front

How does sound travel through different mediums?

Back

Sound travels through air, water, and solids by vibrating particles in those mediums.
