Coherent light with wavelength 598 nm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00 m from the slits. the first-order bright fringe is a distance of 4.84 mm from the center of the central bright fringe
for what wavelength of light will thefirst-order dark fringe be observed at this same point on thescreen?
express your answer in micrometers(not in nanometers).

1.196 μm

Explanation:

D = Screen distance = 3 m

= Wavelength = 598 m

y = Distance of first-order bright fringe from the center of the central bright fringe = 4.84 mm

d = Slit distance

For first dark fringe

Wavelength of first-order dark fringe observed at this same point on the screen is 1.196 μm

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
