Answer:
The distance from the central bright spot are
and
.
Explanation:
Given that,
Wavelength = 490 nm
Distance y= 15 mm
Length L=1.6 m
New wavelength = 670
We need to calculate the distance from the central bright spot
Using formula of distance


Put the value into the formula



We need to calculate the distance from the central bright spot for new wavelength
Using formula of distance

Put the value into the formula



Hence, The distance from the central bright spot are
and
.
