a curved mirror

How big will the angle of reflection be?
20°
40°

Your image in a mirror:
is always smaller than you
is upside down
is always bigger than you
seems to be behind the mirror
Refraction is what happens when light:
hits an opaque object
bounces off a mirror
is scattered unevenly by a rough surface
changes direction as it goes from one substance into another
Refraction occurs because:
light speeds up when it goes from air to glass or water
light slows down when it goes from air to glass or water
light stops when it goes from air to glass or water
light reflects inside transparent materials

sensor
lens
shutter
memory card
Which of these parts of the eye are transparent?
lens only
lens and retina
lens and cornea
lens and iris
Which statement is not correct?
Our retinas have rod cells and cone cells
Rod cells detect different colours
There are three types of cone cells that detect red, blue and green light
Cells in the retina convert energy transferred by light into nerve impulses
Which of these camera parts does not have an equivalent in the eye?
aperture
shutter
sensor
lens
Which statement is not true?

absorbs red light
lets through all colours of light
only lets red light through
changes all the colours into red light
