Why does the straw appear to be bent?
light is reflected
light is absorbed
light is turned
light is refracted
In the illustration, the light ray striking the object is-
What is the angle of reflection equal to?
The angle of refraction
The angle of incidence
The angle of absorption
The angle of light
What can you use to see all the different colors in white light?
A flashlight
A shadow
A camera
A prism
What happens when light hits a shiny or smooth surface?
It disappears.
It is refracted.
It is absorbed.
It is reflected.
What is it called when light bends as it moves from one substance to another?
Absorption
Reflection
Refraction
Incidence
The law of reflection states that
Angle of incidence = Angle of reflection
Angle of incidence = Angle of incidence
Angle of reflection = Angle of translucence
Angle of reflection = Angle of reflection
A concave mirror
Curves inwards
Curves outwards
Curves sideways
Curves in multiple directions
A convex mirror
Curves inwards
Curves outwards
Curves sideways
Curves in multiple directions
Refraction is
The bending of light as it passes through the one substance at an angle
A light beam shone in one end of an optical fibre and totally internally reflected at the other end
The bending of light as it passes from one substance to another at an angle
A type of convex object used in everyday life
Total internal reflection is
When lateral inversion occurs
When the angle of reflection increases up to a critical point where all the light is reflected
When the angle of incidence increases up to a critical point where all the light is reflected
Used in surgery where a light is connected to an optical fibre
