Ascreen is placed 60.0 cm from a single slit, which is illuminated with light of wavelength 690 nm. if the distance between the first and third minima in the diffraction pattern is 3.10 mm, what is the width of the slit?

slit width, b = 0.2671 mm

Given:

distance of screen from the slit, x = 60.0 cm

wavelength of light,

distance between 1st and 3rd minima, t = 3.10 mm =

Solution:

Calculation of the distance between 1st and 3rd minima:

b = 0.2671 mm

slit width, b = 0.2671 mm

are their multiple choices ?

explanation:

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
