When dealing with curve mirrors, all ‘bouncing images’ that are found beyond / behind the mirror:

• real

• imaginary

• different orientation

• incident

If an object was placed in front of a ‘concave lens’ as illustrated below, the ‘bouncing image’ will be:

• longer and virtual

• longer and real

• shorter and virtual

• shorter and real

An incident light travels from glass to air as illustrated. What will be the best representation of light refraction?

• 1

• 2

• 3

• 4

The constant value for velocity of light travels in vacuum.

• 3 x 10⁶ m/s

• 3 x 10⁷ m/s

• 3 x 10⁸ m/s

• 3 x 10⁹ m/s

The index of refraction for air will be:

• 1

• 1.5

• 1.33

• 2.42

When dealing with curve mirrors, all ‘bouncing images’ that are reflected in-front of the mirror is considered:

• real

• imaginary

• same orientation

• incident

When dealing with convex mirrors and an object in-front of the mirror (as illustrated), the Focal point will be:

• 1

• 2

• 3

• 4

When dealing with plane mirrors, the relationship of incident angle and reflected angle will be:

• Ɵ_i = Ɵ_r

• Ɵ_i = Ɵ_r / 2

• Ɵ_i = Ɵ_r²

• Ɵ_i = Ɵ_r + 10°

When you are looking at an object in a plane mirrors, the ‘bouncing image’ will be:

• shorter and inverted

• longer and same orientation

• same height and orientation

• longer and inverted

It is a straight (imaginary) line that is perpendicular with the curve mirror.

• abnormal axis

• principal axis

• tangential axis

• primary axis
