Text Solution
Verified by ExpertsThe correct answer is:
A
We have, 
where, 
and 
are measured in metre, 
is wavelength of wave, whose unit is metre,
is amplitude of wave, whose unit is meter and 
is also in metre (given).
Unit of 
is same as that of 
and 
.
However, unit of 
(speed of light wave) is 
, which is not same as the unit of 
, i.e. metre. Similarly, unit of 
is meter which is not same as the unit of 
, i.e. metre 
.
