Reflection

Question 1

The line joining the image to the object is

Answer 1

Perpendicular to the mirror

Question 2

Angle of incidence

Answer 2

= angle of reflection

Question 3

Angle of incidence

Answer 3

Light going in

Question 4

Angle of reflection

Answer 4

Light bouncing off

Question 5

The normal

Answer 5

A constructed line perpendicular to any reflecting surface at the point where the incident ray hits the surface.

Question 6

The angle of incidence of a light ray at a plane mirror is always

Answer 6

Less than 90 degrees

Question 7

The angle between the normal and the mirror is always

Answer 7

Equal to 90 degrees

Question 8

The angle of incidence of a light ray at a plane mirror is always

Answer 8

Equal to the angle of reflection

Question 9

A normal line is

Answer 9

At right angles to a surface

Question 10

The nature of an image is defined by:

Answer 10

Whether it is upright or inverted
Its size relative to the object
Whether it is real or virtual

Question 11

An image in a plane mirror is

Answer 11

Upright
Virtual
The same size as the object

Question 12

Real image

Answer 12

Can be focused on a screen

Question 13

Virtual image

Answer 13

Can’t be focused on screen- you have to look into the mirror to see it

Question 14

The image

Reflection in plane mirror

Answer 14

Is the same distance behind the mirror as the object is in the front
And the same size as the object
And is virtual (it can not be projected onto a screen)
It is laterally inverted (wrong way round)
