Light

Question 1

Refraction

Answer 1

Refraction is the bending of light as it passes from one medium to another medium of different refractive index’s

Question 2

Laws of refraction

Answer 2

1) the incident ray, reflected ray and normal all lie on the same plane
2) (snells law) the sin of the angle of incidence is proportional to the sin of the angle of refraction

Question 3

Dispersion

Answer 3

Dispersion is the braking up of a beam of white light into its constituent colours which spread out to form a spectrum

Question 4

Laws of reflection

Answer 4

1) The incident ray, reflected ray and normal all lie on the same plane
2) the angle of incidence equals angle of reflection
