  • Q1
    What is light?
    Light is a form of energy
    30s
  • Q2
    What is reflection of light?
    When light falls on a shiny surface, most of it bounces back.
    30s
  • Q3
    What is incident ray?
    The ray of light falling on a reflecting surface is called incident ray
    30s
  • Q4
    What is reflected ray?
    The ray of light coming back from a reflecting surface is called reflected ray.
    30s
  • Q5
    What is normal?
    The perpendicular on reflecting surface at the point of incidence is called normal.
    30s
  • Q6
    What is angle of incidence?
    The angle between incident ray and normal is called angle of incidence
    30s
  • Q7
    What is angle of reflection?
    The angle between reflected ray and normal is called angle of reflection.
    30s
  • Q8
    We can see objects because of
    reflection
    diffraction
    transmission
    refraction
    30s
  • Q9
    When you see a straw in a glass of water it looks bent, why is this
    polarization
    reflection
    refraction
    diffraction
    30s
  • Q10
    Light travels through all transparent media at the same speed
    False
    True
    30s
  • Q11
    What is refraction? Include a real world example as part of your explanation
    Refraction is the bending of light at the interface of two materials with different refractive indices is called refraction. Possible example: A straw in a glass of iced tea looks like it is bent because of the difference in densities and refractive indices of air and the liquid.

  • Q12
    The imaginary line perpendicular to the boundary of two materials or to a reflective surface is called the
    phase line
    reflection path
    normal
    refractive path
    30s
  • Q13
    When a light ray traveling along the normal hits the boundary of two materials, it changes its
    direction
    speed
    30s
  • Q14
    When a ray of light passes from air, a less dense medium, to glass, a more dense medium, the ray of light will bend
    away from normal
    towards the normal
