This is what the light ray is called once it reflects off a mirror.
What is reflected ray
100
True or False: The angle of incidence of a light ray is equal to the angle of refraction
What is false
100
This part of the electromagnetic spectrum is what we can see.
What is the visible spectrum
100

This device helps people see things that are far away by collecting and focusing light.

telescope

100
True or False: The image that is projected onto your retina is right-side-up
What is false - its upside down!
200
This is the light ray that first hits the mirror
What is the incidence ray
200

When light travels from air into water, does the angle decrease or increase?

decreases

200
Name all the colours of the visible spectrum
What is ROYGBIV
200

This type of material lets all the light pass through so you can see clearly.

transparent

200

This is the part of the eye that focuses an image onto the retina.

What is the lens

300
If the angle of incidence is 54 degrees, the angle of reflection will be?
What is 54 degrees
300

This is the reason light bends during refraction.

Change in speed

300
This type of electromagnetic radiation is responsible for the sunburns we experience when we're in the sun too long.
What is UV radiation
300

A wooden door is an example of this type of material.

Opaque

300

This is the coloured part of a human eye. It is also what controls how much light enters the eye.

What is the iris

400

This is the type of reflection that happens when a light ray hits a smooth surface

What is regular reflection

400
In which medium would light travel the slowest: space, air or water?
What is water
400
This type of electromagnetic radiation creates images of our bones on films
What is X-rays
400

What is the difference between a refracting and reflecting telescope?

reflecting: 2 mirrors

refracting: 1 mirror 1 curved mirror

400
This is the one structure that is different between a cow eye and a human eye
What is tapetum
500
This is the type of reflection that occurs when light rays hit an uneven surface (i.e. side of a mountain)
What is diffuse reflection
500

This transparent object causes light to bend and separate into different colors.

What is a prism

500
This type of radiation is also a common way that we heat our food
What is microwaves
500

There are two types of photoreceptors in your eye which ones are for low light vs high light conditions

rods: low light

cones: high light

500
This is a small hole in the center of your eye that lets light it. It's size is controlled by the iris muscle.
What is the pupil.
