Science- Light

Question 1

Ray model of light

Answer 1

Light is represented as a straight line or Ray that shows direction the light wave is travelling

Question 2

Ray

Answer 2

Imaginary line showing direction in which light is travelling

Question 3

Transparent

Answer 3

Allows light to pass through freely

Only small light absorbed and reflected

Question 4

Translucent

Answer 4

Most light rays get through but scattered all directions

Question 5

Opaque

Answer 5

Prevents any light from passing through it

Question 6

Incident Ray

Answer 6

Incoming Ray

Question 7

Reflected Ray

Answer 7

Ray that bounces of barrier

Question 8

Normal

Answer 8

Imaginary line that is perpendicular to the boundary between two materials. Intersects the point at which the incident Ray reaches the boundary

Question 9

Law of reflection

Answer 9

The angle of reflection equals the angle of incidence

Question 10

Angle of refraction

Answer 10

Angle of Ray of light emerging from boundary between the refracted Ray and normal

Question 11

Light density - away

Dense- toward

Answer 11

The normal

Question 12

Concave mirror

Answer 12

Distant- small and upside down
Approaches fp- upside down and larger
Between fp and mirror- upright and larger

Question 13

Convex

Answer 13

Upright and smaller than object

Question 14

Concave lens

Answer 14

Diverge.

Smaller and upright

Question 15

Convex lens

Answer 15

2+ focal length- small and upside down
Between 1-2 - large and upside down
Less than 1- large and upright

Question 16

Particle model of light

Answer 16

Light- stream fast moving unimaginably tiny particles.

Light travel perfect straight line until met the eye-> gets absorbed to make image.
