  • Upright
  • Laterally inverted
  • All of the above
Q.2

  • Newtonian telescope
  • Fiber optic cables
  • A mirror
  • All of the above
Q.3
What is the law of reflection?
  • Angle of incidence = Angle of reflection
  • Angle of incidence < Angle of reflection
  • Angle of incidence > Angle of reflection
  • Angle of incidence = The normal
Q.4

  • Reflected ray
  • Normal
  • Incident ray
  • Ray Charles
Q.5
What is the normal?
  • It is a line perpendicular to the light source
  • It is a line parallel to the reflecting surface at the point of incidence
  • It is a line perpendicular to the reflecting surface at the point of incidence
  • It is a line parallel to the light source
Q.6

  • 32 degrees
  • 68 degrees
  • 58 degrees
  • 122 degrees
Q.7
A ray of light reflects from a plane mirror with an angle of reflection of 64 degrees. What was its angle of incidence?
  • 36 degrees
  • 26 degrees
  • 64 degrees
  • 154 degrees
Q.8
What will all waves do when they are incident, at a certain angle, on surfaces that do not allow the waves to pass through?
  • Diffuse
  • Reflect
  • Disappear
  • Change amplitude
Q.9
Which of the following statements are true?
  • The reflected ray and the incident ray are on opposite sides of the normal
  • The incident ray, the reflected ray and the normal all lie in the same geometric plane
  • The angle of incidence is equal to the angle of reflection
  • All of the above
Q.10
