Monochromatic light falls on two narrow slits that are 0.05 mm apart. The second order bright fringe appears 12 cm from the center maximum on a screen 5 meters away. What is the wavelength of the incident light?

λ = 1.2 x 10⁻⁶ m

Explanation:

Given that,

slit separation,  d = 0.050 mm

                            = 5 x 10⁻⁵ m

Distance between the fringes, D = 5.00 m

distance between the fringes, x = 12.0 cm

                                                    = 0.12 m

wavelength of the light = ?

the separation between the fringe is given by

where as n = 1

λ = 1.2 x 10⁻⁶ m

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
