Question

wavelength Lambda depends upon mass M velocity v and​

Answer 1

frequency is ur correct answer

Answer 2

Ans

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)
