Name ___________________ # ____ St. Mary’s H.S. Physics Reflection and Refraction Review HW Reflection Law or Reflection – Angle of incidence = Angle of Reflection A) all angles are measured with respect to the normal B) Normal – dotted line drawn perpendicular to the surface where the light ray hits the reflecting surface
Measuring Angles – a) Place protractors horizontal guide on the normal b) measure the acute angle between the normal and ray I. Reflection Exercises - For each drawing below: a) Draw the reflected ray b) measure and record the angle of incidence c) and the angle of reflection b) _____ c) _____ b) _____ c) _____ b) _____ c) _____ b) _____ c) _____ (hint: draw the normal first) b) _____ c) _____ b) _____ c) _____
