1
New cards

refraction

light changes direction when going between mediums

2
New cards

speed of light in a vaccum

3×10^8 m/s

3
New cards

speed of light in glass

200 000 m/s

4
New cards

sped of light in water

225 000 000 m/s

5
New cards

refractive index

ratio of speed of light in a vaccum to the speed of light in a medium

6
New cards

refractive index formula

n=c/v

7
New cards

travelling on the normal

no refraction

8
New cards

less dense to more dense

bends towards the normal and light moves slower

9
New cards

more dense to less dense

bends away from the normal and light moves faster

10
New cards

snells law

n1sin1θ1=n2sin2θ2

11
New cards

wavelength

gamma-x-ray-uv-violet to red-infrared-microwaves-radiowaves

12
New cards

wave length info

frequency decreases and wavelength increases
