Light

Question 1

What is light?

Answer 1

1. Electromagnetic waves
   
   1. made of electric: movements of charges
   2. made of magnetic: forces around the movement of charges

Question 2

What is the relationship within wavelength and frequency?

Answer 2

1. high frequency low wavelength
2. low frequency high wavelength

Question 3

What is the reflection angle?

Answer 3

1. It is an angle that is bouncing off the surface it is not going through/

Question 4

What is the angle of refractions?

Answer 4

1. This is an agle that is created when light travels through different mediums.

Varialble

1. C= light in a vacuum ( the fastest way light travels)
2. V = velocity of light in any other medium
3. n = a number that tells us how different medium impacts the speed of light. It is different from one medium to the next
   
   1. n water = 1.33
   2. n air = 1

Question 5

Where does light move the fastest?

Answer 5

1. vacuum
2. air
3. water
4. solid

Light travels in transvers waves

Question 6

What is the incident light rays?

Answer 6

1. The light ray will always be drawn according to the perpendicular line that allows us to get either a refraction or reflection angle.

Question 7

What is the difference between the reflected and refracted light rays ? what is the incident line?

Answer 7

1. Refracted: light is hitting another medium
2. Reflected: bounce the off of the surface
3. line of incident: is the line that allows us to determine both the refraction and reflections angle.

Question 8

What does the snell law help us do?

Answer 8

• The snell law helps us connect the n value ( that is dependent on the substance) and understanf how they come into play to help is calculate the refractions angle especially if they are given.

Question 9

What is the critical angle? and totla internal relfection****

Answer 9

1. This is an angle that gives us insight into what the light will end up behaving
2. light coming from water to air ( total
   
   1. incidend ray will try and reach the zero
   2. refracted light ray will move 90 degrees
3. light coming from water to air ( total internal reflections)
   1.

Question 10

What is dispersion?

Answer 10

• It is the concept of how we see rainbows, light can bend at different interface in an object, the drawing befroe the light was hitting linears things
• when light hit the surface it will cause light to split in their different wavelengths and emit different colors.

Question 11

Which light refract the least?

Which has the largest intensity?

Which has the smallest intensity?

Answer 11

1. Red
2. Blue
3. Green?
