If the eighth bright band due to light of wavelength `lamda_(1)` and coincides with ninth bright band from light of wavelength `lamda_(2)` is young's double slit experiment, then the possible wavelength of visible light are

A

400 nm and 450 nm

B

425 nm and 400 nm

C

400 nm and 425 nm

D

450 nm and 400 nm

Text Solution

Verified by Experts

The correct Answer is:
D
`(8lambda_(1)D)/(d)= (9lambda_(2)D)/(d) implies 8 lambda_(1)= 9 lambda_(2)`
Only (d) option is correct.
