Reflection of waves

Question 1

Can all waves be reflected?

Answer 1

yes

Question 2

Does reflection of lights lets us see things?

Answer 2

yes

Question 3

is visible light transverse wave or longitudinal waves

Answer 3

transverse wave

Question 4

How does light allow us to see an object?

Answer 4

2) Reflection of visible light is what allows us to see most objects. Light bounces off them into our eyes.

Question 5

what happens when light reflects from an uneven surface?

Answer 5

3) When light reflects from an uneven surface such as a piece of paper, the light reflects off at all different angles and you get a diffuse reflection.

Question 6

what happens when light reflects from an even surface?

Answer 6

When light reflects from an even surface (smooth and shiny like a mirror) then it’s all reflected at the same angle and you get a clear reflection.

Question 7

what is the law of reflection?

Answer 7

The law of reflection applies to every reflected ray:

Angle of incidence = Angle of reflection

Question 8

What is normal in the law of reflection?

Answer 8

The normal is an imaginary line that’s perpendicular (at right angles) to the surface at the point of incidence (the point where the wave hits the boundary). The normal is usually shown as a dotted line.

Question 9

what is the angle of incidence and what is the angle of reflection?

Answer 9

The angle of incidence is the angle between the incoming wave and the normal. The angle of reflection is the angle between the reflected wave and the normal.

Question 10

Describe the properties of light waves?

Answer 10

• Transverse wave
• Transfer energy
• Can be reflected, refracted, diffracted
• A wave where vibrations occur perpendicular to the direction the wave is travelling
