Explanation:
Person A's velocity relative to the train is 0. Therefore, the pitch of the horn will not change.
Answer:
6.02 radian
Explanation:
At 12 noon position is zero radian on Monday
at 12 midnight the position is π/2
at 11 am position on Tuesday is 2π/24 x 23 ( after 23 hours ) = 6..02 radian.
Explanation:
It is given that,
Wavelength of monochromatic light, 
Slits separation, 
(a) We need to find the angle corresponding to the first bright fringe. For bright fringe the equation is given as :
, n = 1



(b) We need to find the angle corresponding to the second dark fringe, n = 1
So, 




Hence, this is the required solution.
