Question

The wavelength associated with a moving particle depends upon pth power of its mass m, oth power of its velocity v and rth power of
Planck's constant h. Then, the correct set of values of p, 9 and r is (E = hv, E is the energy of a wave, v is frequency & h is planks
constant)​

Answer 1

Explanation:

wavelength is h/mv

so p is -1

o is -1

r is +1

hope this helps u mate

Answer 2

Answer:

wavelength dimension=[L]

mass dimension=[M]

velocity dimension= [LT^-1]

plank constant dimension=[ML^2T^-1]

now

[L]=k [M]^a [LT^-1] ^b [ML^2T^-1] ^c

=k [M]^(a+c)[L]^(b+2c)[T]^(-b-c)

compare LHS to RHS

a+c=0

b+2c=1

-b-c=0

so

c=1

b=-1

a=-1

hence

lemda=k .plank constant/(mass. velocity)
