2. n21=_____
3. Snell's law=______
4. At_____the incident ray do not bent.
5. The formula for relative refractive index is_____
6. The speed of light in water is_____
7. The units of 'G' is______
8. Acceleration is_______/ mass
9. 8 kg body weights______Newton on Earth
10. If there is no gravity, then the weight of 10 kg object is_______
​

Answer 1

Answer:

1) n=c/v

2)sin i/ sin r = constant = n21

3)snell' s law given the degree of refraction and relation between the angle of incidence the angle of refraction and refractive indices of a given Pair of media.snell's law fromula

n1 sin1=N2 sin2
