1.) A laser beam is reflected by a plane mirror. It is observed that the angle between the incident and reflected beams is 30. What is the angle of reflection? Explain

2.) A ray of light strikes a plane mirror with an angle of 30 above the horizon.
What is the angle of incident?
What is the angle of reflection?
Show your work

3.) Looking at the figure on the side? (attached)
How many times will the light strike the top of the mirror?
The distance between the two parallel mirrors is 70 cm, and the length of each mirror is 100cm

thank you to anyone who will solve it <3

Intro: a solid ball of radius rb has a uniform charge density ρ. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of ρ, rb, r, and ϵ0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of ρ, rb, r, and ϵ0. part c: let e(r) represent the electric field due to the charged ball throughout all of space. which of the following statements about the electric field are true? check all that apply. e(0) = 0 e(rb)=0 limr→∞e(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as r→∞.
