If change in energy (DeltaE)=3xx10^(-8) ...

If change in energy `(DeltaE)=3xx10^(-8)` J, `h=6.64xx10^(-34)` J-s and `c=3xx10^8`m/s, then wavelength of the light is

A

`6.36xx10^(3)Å`

B

`6.36xx10^(5)Å`

C

`6.64xx10^(-8)Å`

D

`6.36xx10^(18)Å`

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaE=(hc)/lamdaorlamda=(hc)/(DeltaE)`
`=(6.64xx10^(-34)xx3xx10^(8))/(3xx10^(-8))=6.64xx10^(-8)Å`.
