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
The three primary colours of light are
What is red, green, blue
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 goes from a less dense medium such as air to a more dense medium such as water, does the light refract towards the "normal line" or away?

What is towards the "normal line"

200
Name all the colours of the visible spectrum
What is ROYGBIV
200
This colour is produced when blue and green light are mixed together
What is cyan
200
This is the part of the eye that focuses an image onto the retina. It shares the same name as a part of your glasses
What is the lens
300
If the angle of incidence is 54 degrees, the angle of reflection will be?
What is 54 degrees
300

What causes the light to bend (refract) when going from one medium to another?

What is 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
This colour of light is produced when red and green light are mixed together
What is yellow
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 specular 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
This model of colour explains what is produced when different colours of light are mixed together
What is the additive model of colour
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
The refractive index of air is 1.0003 and the refractive index of crown glass is 1.52. In which material would light travel the fastest?
What is air
500
This type of radiation is also a common way that we heat our food
What is microwaves
500

Why does a green laser pointer pop a black balloon but won't pop a green or white balloon

What is the black balloon absorbs the light energy converting it to thermal energy. The green and white balloon reflect the green 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.
