Form of energy that propagates without a medium and allows us to see
What is light
100
How light travels. The reason it makes sharp shadow lines
What is travels in straight lines
100
The reason light bends when going from air into glass
What is it slows down
100
The angle that light strikes a surface and the angle it reflects off the surface have this in common
What is the same value
100
Where the rays of a lens come together
What is the focal point
200
Very early scientist who studied light. His name rhymes with "bottle"
Who is Aristotle
200
Two basic ways that light can be "bent". (Hint: only two letters difference between the two)
What is reflection and refraction
200
The angle light strikes a surface relative to a perpendicular line is called this
What is the angle of incidence
200
When light stays trapped inside an object such as an optical fibre (Hint: 3 words)
What is total internal reflection
200
Scientific name for light rays coming together and moving apart
What is converging and diverging
300
Was the the first scientist to experiment with light splitting into it's component colours
Who is Sir Isaac Newton
300
Scientific word for light traveling through a transparent substance
What is transmission
300
The line perpendicular to the surface where light penetrates is known as. (Hint: most teachers are not this)
What is Normal
300
A type of mirror where the light rays meet once reflected
What is a concave mirror
300
A magnifying glass makes this type of image because the light rays don't actually meet
What is virtual
400
The two basic types of light sources
What are natural and man-made (artificial)
400
This property of light allows a light house to spread light in all directions when the fog is out
What is scattering
400
When traveling from a more dense to a less dense substance, light will bend this way relative to the perpendicular
What is away from the normal
400
The type of mirror where you may appear upside-down
What is a concave mirror
400
Why a red shirt looks red
What is it reflects red light and absorbs the other colours
500
The duality of light argues that light is both of these
What is a particle and a wave
500
This happens when light strikes a surface and doesn't go through or bounce back
What is absorption
500
Light leaving a more dense substance to a more dense substance can bend so much it reaches this and skims along the surface of the object (Hint: two words)
What is critical angle
500
Where the light rays "meet" in a convex mirror
What is behind the mirror
500
A red filter subtracts blue light from this colour of light
