Calculating Angle Deflection in Laser-Mirror Interactions

Click For Summary

Homework Help Overview

The discussion revolves around calculating the angle of deflection in a scenario involving a laser beam and a mirror. The original poster presents a problem where a horizontal laser beam is deflected by a specified angle, and they seek to determine another angle related to this setup.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between the angles involved, with one suggesting that the unknown angle may be the angle of incidence. Questions about the placement of angles in a diagram are raised, indicating a need for clarification on the visual representation of the problem.

Discussion Status

The discussion is ongoing, with participants seeking to clarify the setup and relationships between the angles. Some guidance has been offered regarding the importance of diagrams and the placement of angles, but no consensus has been reached on the interpretation of the angles involved.

Contextual Notes

The original poster has not provided a diagram, which seems to be a crucial element for understanding the problem. There is also ambiguity regarding the definitions and placements of the angles mentioned.

Mirror and laser beam angle...please help!

Homework Statement


The mirror deflects a horizontal laser beam by θ=59°. What is the angle φ?


Homework Equations





The Attempt at a Solution


I don't understand this. How am I supposed to figure out φ?
 
Physics news on Phys.org
I assume φ is the angle of incidence.

Have you drawn a diagram?

What have you drawn … ? :smile:
 
I have the beam being reflected with lines drawn the upper left and lower left
 
You haven't told us where you've put the 59º in, nor where you've marked φ.

So … where are they?

Anyway, how much are the upper left and lower left angles? :smile:
