Refraction of Light

• What happens to the speed of light as it passes through a different medium?

  It changes speed.
• What happens when the light rays passes from a less dense to a denser medium?

  It bends toward the normal
• What happens when light ray passes from a denser to a less dense medium?

  It bends away from the normal.
• Which is not a characteristic of an image formed by a concave lens? A. Upright , B. Small , C. Inverted , D. Virtual

  B. Inverted
• Which is not a characteristic of an image formed by a convex lens? A. Real and Inverted , B. Virtual and Upright , C. Real and Upright , D. None of the above

  Real and Inverted
• The refraction of light is the bending of light as it passes through different mediums.
• When a ray of light travels from a vacuum to a denser medium such as glass, it is refracted towards the normal.
• When a ray of light travels from glass to air, it is refracted away from the normal.
• What is the refraction index of air?

  1.00
• What is the refraction index of water?

  1.33
• Which of the following shows a convex lens?

  Right

  
• Optical Density is related to the transparency of a substance to light; the higher the optical density of a material, the slower the light travels through it.
