smaller
In the image, all the rays meet at F, What is F
focal length

A student placed a pencil in a cup of water. The pencil appears broken because light
always travels in a straight line.
bends when it passes through water.
makes the water in the glass evaporate.
reflects the pencil on the water's surface.
When light passes at an angle to the normal from one medium into another in which its speed is higher
it is bent toward the normal.
it always lies along the normal.
it is unaffected.
it is bent away from the normal.
When light passes at an angle to the normal from one medium into another in which its speed is lower
it is bent towards the normal.
it always lies along the normal.
it is unaffected.
it is bent away from the normal.
Why is the spectrum of light separated into its components of color when white light is directed to a prism?
Because light reflects off the prism's surface
The incident white light refracts and separates into its constituent colors
The white light is absorbed by the prism, separating its colors
The light speeds up as it moves from air into the denser plastic material
Why does the straw appear to be bent?
light is reflected
light is absorbed
light is turned
light is refracted
What do we call a material that light can travel through?
air
water
medium
pathway
Objects that reflect well are
Matte surfaces
Smooth, shiny surfaces
Dark coloured surfaces
Medium coloured surfaces
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
This is the example of dispersion of light
sky looks bright orange in the evening
shadow
Pool seems shallower
rainbow
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
