Light review

Why do we see a GREEN leaf?

• because humans color it that color
• because it absorbs green and reflects all the other colors
• it absorbs every color except for green

Why do we see objects as white?

• They absorb all light
• They reflect all light
• They absorb some light and reflect some light

Why does a pencil with one end in the air and one end under water appear bent?

• Light moves through air faster than it moves through water.

• The light is reflected from the pencil moves in a curved path.

• Light moves through water at the same speed as it moves through air.

• Light in the air is brighter than light in the water.

What is the incident ray?

• The ray light refracts in the medium

• The ray of light that reflects off the medium

• The ray of light that enters an object

• The ray of light that scatters

Light waves need matter to travel.

• True
• False

When light travels from air to water it....

• Speeds up

• Slows down

• stays the same speed

A wave acts like a...

• wave

• particle

• particle and a wave

• neither a particle or a wave

White light is made up of

• Absorbing colors
• All the colors of the rainbow
• Red and Blue light

What is the correct order of the visible light spectrum from longest to shortest wavelength?

• 1

• 2

• 3

• 4

What is the difference between the different types of electromagnetic radiation in the visible spectrum?

• The ability to reflect and therefore the wavelengths of the types of electromagnetic radiation are different.

• The ability to transmit and therefore the wavelengths of the types of electromagnetic radiation are different.

• The amount of energy and therefore the wavelengths of the types of electromagnetic radiation are different.

• The amount of refraction and therefore the wavelengths of the types of electromagnetic radiation are different
