Q. Assertion :Kepler's second law can be understood by conservation of angular momentum principle. Reason: Kepler's second law is related with areal velocity which can further be proved to be based on conservation of angular momentum as

(d A / d t) = (r^{2} ω) / 2

Q. Using Huygens principle show that , for a parallel beam incident on a reflecting surface the angle of incidence is equal to the angle of reflection

1. how can angle of incidence is =angle of refraction

in case of reflection it is possible according to law .but reflection is not similar to refraction?

2.as it is said angle of incidence is =angle of emergence.then we can say that when angle of incidence increases then angle of emergence also increases?iam right.
