Light whose wavelength is 633nm falls on a double slit with spacing of 0.100mm. what is the separation between the 0th and 1st order peak on a screen, l=1.20m from the double slit?

Approximately 0.00760 m (that's 7.60 mm.)

Explanation:

Refer to the first diagram attached. For a double-slit diffraction, the angle (angular separation) between the m-th maximum and the central maximum satisfies the following equation:

, where

(Young’s Double Slit Experiment, OpenStaxCollege)

If is much larger than , the value of will be considerably small. The value of could thus be approximately as:

.

For this problem,

Approximate the value of :

.

Separation between the first and central maximum:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
