Which of the following is NOT a property of an image formed by a plane mirror?
virtual
laterially inverted
upside down
same size
Which type of mirror forms a small field of vision with enlarged objects?
plane mirror
concave mirror
convex mirror
rear-view mirror
Rough surfaces do not form an image because
there is no reflection on rough surfaces
the reflected rays are at different angles
the reflected rays are parallel
the reflected images are undistorted and clear
A ray of light travelling in another medium at a different speed is known as the
normal
incident ray
refracted ray
emergent ray
A glass prism can be used to split white light into its component colours. This is known as (a) of light.
When light rays move from an optically denser medium to a less dense medium, light rays move (a) the normal.
Light travels slower and bends more towards the normal is a (a) (more/less) optically dense medium.
Light travels from n1 to n2. Based on the refraction of light, determine if n1 or n2 is an optically denser medium.
n1 > n2
n2 > n1
same optical densities
