refraction

when does refraction happen

when the light passes through two medians

why does the light travel slower when it travels through a more denser median h

because there are more particles that then slows down the light, creating refraction.

what is snells low (plus formula)

describes how the light bends when going through two different medians.

n1 sin I = n2 sin r

n1 is the refractive index 1st Median

n2 is the refractive idnerxx 2nd median

sin I is incidence angle

sin r is refractive angle

A ray of light travels from air into glass.

• Refractive index of air: n1=1.0n1​=1.0

• Refractive index of glass: n2=1.5n2​=1.5

• Angle of incidence: i=30∘i=30∘

find the refraction angle

n1 sin I = n2 sin r

1 sin (30) = 1.5 sin R

sin (30) =0.5

0.5 × 1 =0.5

0.5 = 1.5 sin R

0.5 / 1.5 =0.333

sin -1 (0.333) =r

19.5 = r

what is the C in CORMMS for refraction practical

C is Change

It will be the angle of the incidence

What is the O in CORMMS in this practical

organism / material

Block of glass

What is the R in CORMMS in this practical

R is repeat

repeat three times and create average to have reliable data

what is the first M ion the CORMMS in this practical

M is measurement

measuring the angle of the refraction using protractor

What is the second M in the CORMMS in this practical

don’t know

What is the S in CORMMS in the practical

same light source

S is same
