Eight Standard

Test your understanding of this lesson Laws of reflection:-

1)
The angle of incidence and the angle of reflection are measured w.r.t-
  • The surface of reflection
  • The plane of incidence
  • Horizontal axis
  • Normal drawn at the point of incidence
2)
The angle of incidence and the angle of reflections-
  • Angle of incidence is always greater
  • Angle of reflection is always greater
  • They are always equal
  • None of above
3)
The normal is drawn –
  • Anywhere on the plane of incidence
  • Perpendicular to the incident ray
  • Perpendicular to the reflector at the point of incidence
  • Perpendicular to the reflected ray
4)
The incident and reflected ray along with the normal-
  • Must coincide at a point
  • Must lie in the same plane
  • The normal may lie on any plane
  • There is no such restriction
5)
Angle of reflection depends on-
  • The colour of light
  • On the angle of incidence
  • Both (a) & (b)
  • Independent of (a) and (b)
