Light Reflection & Refraction

The following diagram shows the ray diagram when a torch light is torched towards a mirror. Which of the following is the correct reflected ray?

• 
• 
• 
• 

When does the light is refracted?

• When light travels in a straight line

• When light is bounced

• When light travels in two different mediums

• When light cannot pass through an opaque object

Diagram shows the condition of a spoon in a glass of water.

What can be observed about the spoon?

• The spoon looks bent.

• The water is clearer.

• The water level rises.

• Light is refracted.

When light hits an area and bounces back it is called:

• echo

• refraction

• reflection

• absorbing

What is the angle of reflection (θ_r) in the image?

• 56^o

• 90^o

• 124^o

• 34^o

When the light passes out of the glass, back into the air

• It bends away from the normal

• It does not bend

• It bends towards the normal

• It continues to be the normal

The ray of light that strikes a reflecting surface is called ________.

• incident ray
• reflected ray
• normal ray
• none of the above

Why can you see most objects? 

• they emit light
• light refracts through them
• light reflects off them
• They absorb light

Law of reflection state that - The angle of incidence is .................. to the angle of reflection.

• equal
• double
• half

What is the angle of reflection equal to?

• The angle of refraction

• The angle of incidence

• The angle of absorption

• The angle of light
