light

Question 1

Types of ray lights

Answer 1

Convergent rays
Parallel rays
Divergent rays

Question 2

Luminous and non luminous light

Answer 2

Luminous:
Emit light
Light travels in a straight line

Non-luminous
Do not emit light
Light from light source is reflected off object and enter our eyes

Question 3

When light is incident on an object, can undergo: _____________________________

Answer 3

Reflection
Refraction
Absorption
Dispersion

Question 4

Reflection of light

Answer 4

Bouncing of light off a surface
Can see non-luminous objects as light os reflected off them

Question 5

Characteristics of images formed by plane mirrors

Answer 5

Virtual
Upright
Image is same size as object
Laterally inverted
The perpendicular object distance is equal to the perpendicular image distance

Question 6

Concave and convex
Bends which direction?
Images formed? (3 of them)
Uses?

Answer 6

Concave:
Mirror with curved surfaces that bends inwards

Image formed:
Virtual
Upright
Magnified (enlarged)

Convex:
Mirror with curved surfaces that bends outwards

Image formed:
Virtual
Upright
Diminished (small)

Question 7

Refractive index formula

Answer 7

N=c/v

N-refractive index
C-speed of light in vaccum (3.00*10 to the power of 8)
V-speed of light in medium
