Light Waves

Question 1

Can light waves travel through matter

Answer 1

Yes light waves are transparent ans longitudinal yes too (solid, liquid, gas)

Question 2

There speed of travel is

Answer 2

For transverse 3x 10. 8 m/s and longitudinal is 300 m/s

Question 3

Why can you see lightning before thunder

Answer 3

The light travels faster than sound. Therefore the light from the lighting we see because it travels faster

Question 4

Can they travel through vaccum

Answer 4

Transverse yes longitude no

Question 5

Why can we see non lumonos objects?

Because they create there own light we can see them becasue they reflect into our eyes

Question 6

Answer 6

A shadow is made when an object blocks light

Question 7

Reflection of light

Answer 7

When a surface is light and all the ray bounces off a mirror without being scatterd

Question 8

Laws of reflection

Answer 8

1 the angle of incidence is equal to angle of reflection

2 the incidet ray , the reflected ray and the normal point of the incidence lie in the same plane.

Question 9

Refraction of light

Answer 9

Any material that light can travel through is called a meduim when light rays travel from one mediuem yo another they bend

Question 10

How the refraction of light occurs

Answer 10

The light bends because it travels more slowely in glass than it does in air.
