Explanation:
It is given that,
Initial state of electron,
Final state of electron,
The wavelength of the excited electron is given by :
Where
R is Rydberg's constant
or
Let f is the frequency of the observed photon. It is given by :
Hence, this is the required solution.
IT should be c a decreased wave frequency.
I don't know man I could be wrong. papa bless
Answer:3
Explanation:
First ball is thrown with horizontal velocity while other ball is dropped from cliff such that both have zero vertical velocity. So both balls have to cover a distance equal to the height of cliff with same initial velocity.
time taken is given by
where h=height of cliff
g=acceleration due to gravity
horizontal velocity to first ball will make the ball to travel more horizontal distance as compared to second ball.
Option 3 is correct
