Kyle lays a mirror flat on the floor and aims a laser at the mirror. the laser beam reflects off the mirror and strikes an adjacent wall. the plane of the incident and reflected beams is perpendicular to the wall. the beam from the laser strikes the mirror at a distance =55.9 cm from the wall. the reflected beam strikes the wall at a height =38.9 cm above the surface of the mirror. find the angle of incidence thetai at which the laser beam strikes the mirror.

θr = 55.2 °

Explanation:

The law of reflection states that the angle of incidence and the angles of reflection is the same.

Let's use trigonometry to find the angle between the reflected ray, where the horizontal distance x = 55.9 cm and the vertical distance is y = 38.9 cm

    tan θ = y / x

    tan θ = 38.9 / 55.9

    θ = tan⁻¹ (0.6959)

    θ = 34.8°

This angle is measured with respect to the x-axis (horizontal), but in general the angles in optics are measured from the y-axis so that the angle is

    θ = 90 - 34.8

    θr = 55.2 °

answer; i believe the correct answer is (40,000 j) good luck

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
