Question

Which physical quality is represented by √λ×√g where λ is wavelength and g is acceleration due to gravity: *

0/1

Speed

Acceleration

 

Force

Time

explain it tooo​

Answer 1

ANSWER

Since λ is wavelength, hence its dimension is that of length = L.

Dimension of g is LT

−2

Thus, dimension of

λg

=

L

2

T

−2

=LT

−1

, which represents velocity.
