  1. 1. What is dispersion of light?

    • A. The splitting of white light into its component colours when it passes through a prism due to different frequencies having different refractive indices
    • B. The bending of light as it passes from one medium to another
    • C. The scattering of light in all directions when it hits a rough surface
    • D. The absorption of light by a transparent material
  2. 2. Which colour has the highest frequency in the visible spectrum?

    • A. Red
    • B. Green
    • C. Violet
    • D. Orange
  3. 3. Why do different colours of light refract by different amounts when entering a glass prism?

    • A. Because different colours have different speeds in the glass, caused by their different frequencies having different refractive indices
    • B. Because the prism is made of different materials in different sections
    • C. Because different colours have different intensities of light
    • D. Because red light is absorbed more than violet light
  4. 4. What is monochromatic light?

    • A. Light that has been reflected by a mirror surface
    • B. Light that consists of a single frequency, appearing as one pure colour
    • C. Light that has been completely absorbed by a material
    • D. Light that has been split into multiple colours by a prism
  5. 5. When white light passes through a glass prism and disperses into its spectrum, which colour will be refracted the most and which the least?

    • A. Red refracted most, violet refracted least
    • B. Violet refracted most, red refracted least
    • C. Orange refracted most, indigo refracted least
    • D. Green refracted equally to both red and violet
