Suppose Young's experiment is performed with blue-green light of wavelength 500 nm. The slits are 1.40 mm apart, and the viewing screen is 5.50 m from the slits. How far apart are the bright fringes near the center of the interference pattern

what question you dont ask a question

explanation:

1/0.14nm = 10^10/1.4 a lot

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
