The gravity in the space shuttle is approximately equal to the gravity on the surface of the earth
Answer:
λ = 864 nm
Explanation:
To find the wavelength of the light you use the following formula, which determines the position of the m-th fringe in an interference pattern:
(1)
ym: position of a bright fringe
D: distance from the slits to the screen = 3,7 m
d: distance between slits = 0,2mm = 0,2 *10^-3 m
m: order of the fringe
λ: wavelength of the light
You have the distance from the central peak to the third fringe (0,048m). Then, you can use the equation (1) with m=3 and solve for the wavelength:
henc, the wavelength of the light is 864nm
A good engineer will create an outline that meets the useful necessities of the venture and after that play out an anxiety examination to get certainty that the tower will be sheltered under the normal scope of working conditions. By then, the outline will be tastefully satisfying to engineers. On the off chance that the customer needs something all the more stylishly cleaned, he may need to utilize a plan authority. A designer who puts feel initially is taking a chance with his expert standing.
