What is path length or Range of S.H.M ?

At what distance from the mean position is the speed of the particle, performing S.H.M half its maximum speed. Given path length of S.H.M is10 cm .

What is phase of S.H.M.

Explain what is optical path length . How is it different from actual path length ?

The term phase in S.H.M

State examples of S.H.M

The path length of oscillation of simple pendulum of length 1 m is 16 cm. Its maximum velocity is (take, g=pi^(2)m//s^(2) )

A projectile is thrown at an angle of 30^@ to the horizontal. What should be the range of initial velocity (u) so that its range will be between 40m and 50 m? Assume g= 10 m s^(-2) .
