16. Reflection of Light

---

1. The rays falling on any surface are called ................... 1) normal rays 2) Reflected rays 3) incident rays 4) mirror

2. if Angle of incidence is 30 degree to the normal in flat mirror then find Angle of reflection? 1) 30 2) 50 3) 60 4) 120

3. in Periscope two mirrors makes angle of ------------------ with the sides of the box and are parallel to each other. 1) 60 degree 2) 90 degree 3) 45 degree 4) 100 degree

4. If the reflected ray makes an angle of 60 d. with the nomal, what angle must the incident ray make with the normal? 1) 30 2) 120 3) 90 4) 60

5. If the angle between the incident ray and the reflected ray is 900, what are the values of the angle of incidence and angle of reflection? 1) 90 2) 55 3) 60 4) 45

6. What angle will the reflected ray make with the mirror if the angle of incidence is 400 ? 1) 90 2) 60 3) 40 4) 50

7. If the angle between the mirror and reflected ray is 23 d., what is the angle of incidence of the incident ray? 1) 167 2) 67 3) 23 4) 87

8. Find correct name for A and B? 1) None of these 2) both 3) A- Reflected ray, B-Incident ray 4) A -Incident ray, B - Reflected ray
