Question 1

WHAT IS REFLECTION

Answer 1

It is when light bounces off an object

Question 2

When we look at objects what are we seeing

Answer 2

We are seeing the light reflecting off them

Question 3

Explain what is an incident ray

Answer 3

The ray of light that is gong to strike a surface

Question 4

What is a reflected ray

Answer 4

The ray of light that bounces off an object

Question 5

What is a normal

Answer 5

A reference line drawn perpendicular to the reflecting surface at te point where reflection occurs . It’s not a ray of light . Al measurements are taken from this line

Question 6

.What is the angle of incidence

Answer 6

Angle between the incident ray and the normal

Question 7

What is the Angle of reflection

Answer 7

The angle between the reflected ray and the normal

Question 8

State the law of reflection

Answer 8

Law of Reflection : The angle of incidence and the angle of reflection are equal ( î = r)

Question 9

Name the two types of reflectio

Answer 9

regular reflection

Diffuse ( scattered ) reflection

Question 10

Explain what is regular reflection

Answer 10

On smooth and highly polished , all light is reflected in the same direction ,enabling you to see an image
Example: mirror

Question 11

Explain and give examples of diffuse reflection

Answer 11

On rough surfaces , reflected light is scattered in many directions , you can’t see an image but te surface appears shiny or white
Example : sheet of paper , clouds
