Refraction Of Light

Question 1

Refraction

Answer 1

The bending or change in direction of light when it travels from one medium into another

Question 2

Factors affecting the refraction of light

Answer 2

Speed of light in different media/ wavelength of light/ angle of incidence

Question 3

Speed if light in different media

Answer 3

The density of the material through which the light is moving can slow down the light due to greater interaction which atoms in the way

Question 4

Wavelength of light

Answer 4

The angle of light is related to how much energy they have. This impacts how much the light twists when it shifts from one medium to another

Question 5

Angle of incidence

Answer 5

Just that 🤷‍♀️

Question 6

1st rule of refraction

Answer 6

The oath of light will bend towards the normal when it transitions from a fast medium, and moves into a slow medium

Question 7

2nd rule of refraction.

Answer 7

When light moves from a slow medium into a FAST medium, the path of light will bend AWAY from the normal

Question 8

Apparent depth

Answer 8

When light from an object in water is observed by someone outside of the water from an angle the refraction of light lead to an illusion related to position and depth

Question 9

Mirage

Answer 9

A mirage is the illusory perception of water where there is none. The reflection of light off of the water is the only example in nature where light is reflected from ground level

Question 10

Mirage pt. 2

Answer 10

A mirage is caused bye the refraction of light as it moves through air at different temperatures over a hot surface

Question 11

Refraction and critical angle

Answer 11

When the light is bent such that its angle of refraction is 90 degrees we have reached what is known as the critical angle. Beyond this point light is reflected back into the og medium

Question 12

Critical angle

Answer 12

The critical angle is the incident angle beyond which light will no longer be refracted but will be reflected back into the medium

Question 13

Total internat reflection

Answer 13

Once we exceed the critical angle total internal reflection occurs where all light is reflected back into the medium. The rules of reflection apply at this point rather than the laws of refraction.

Question 14

Fiver option cables

Answer 14

Fiver optic cables allow transmission of info at the speed if light rather than relying on the flow of electricity, it works via total inertial reflection of light along a cable with a low critical angle

Question 15

Diamond

Answer 15

Diamonds are sparkly because of total internal reflection. Gem cutters will cut crystals at specific angles in order to maximize the sparkle of the gem stone.

Question 16

Periscope

Answer 16

Also use total internal reflection creating a clear image
