1
Q
Refraction
A
Refraction is the bending of light when it travels from one medium to another
2
Q
Refractive index formula
A
Sin i over sin R speed of light in vacuum over speed of light in
medium
3
Q
Explain what is meant by the critical angle for a ray of light
A
Angle of incidence resulting in an angle of refraction of 90 degrees, beyond this angle the ray is totally internally reflected. Ray travelling from optically dense medium to less dense medium
