In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 47.0 km due north. A detector is placed 119 m due east of the laser. The mirror is to be aligned so that light from the laser reflects into the detector.(a) When properly aligned, what angle should the normal to the surface of the mirror make with due south?

The incidence angle is 0.145°.

Explanation:

Given that,

Distance due to east = 119 m

Distance due to north= 47.0 km

We need to calculate the incidence angle

Using formula of incidence angle

Where, y = distance due to north

x = distance due to east

Put the value into the formula

Hence, The incidence angle is 0.145°.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
