Question

If radius of 2nd Bohr's orbit is x, then de-Broglie
wavelength in 4th orbit is given by :​

Answer 1

Answer:

when n = orbit no.

so, R4 = 4²*(R1) = 16x

now from the relation

mvr = nh/2π 

=> mv(16x) = 4h/2π 

=> 2h/π = 16mvx 

=> h/mv = 8πx...

and h/mv is the wave length.

so, option 1
