Alaser beam of wavelength 600 nm is incident on two slits that are separated by 0.02 mm. what is the separation between adjacent bright maxima observed on a screen 5 m away? (a) 1.1 mm (b) 0.625 mm (c) 20 mm (d) 15 cm (e) 0.1 mm

option D

Explanation:

given,

wavelength = 600 nm

width of separation = 0.02 mm

L = 5 m

for mth order maxima

for (m+1)th order maxima

now,

     and

hence,

hence, the correct answer is option D

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get
