  1. Question 1

    The James Webb Space Telescope uses gold-coated mirrors. Why gold?

    • A. Gold absorbs infrared light
    • B. Gold is magnetic
    • C. Gold reflects infrared light very well
    • D. Gold makes the telescope heavier

  2. Question 2

    A ray of light hits a flat mirror with an angle of incidence of 25°. What is the angle of reflection, in degrees?

    Answer°

  3. Question 3

    A ray of light makes an angle of 75° with the surface of a mirror. What is the angle of reflection, in degrees?

    Answer°

  4. Question 4

    How does an image in a flat mirror compare with the object?

    • A. smaller and upside down
    • B. same size, upright and laterally inverted (left–right swapped)
    • C. the same in every way
    • D. larger and upright

  5. Question 5

    A ray of light hits a flat mirror with an angle of incidence of 25°. What is the angle of reflection, in degrees?

    Answer°

  6. Question 6

    A ray of light makes an angle of 50° with the surface of a mirror. What is the angle between the incident ray and the reflected ray, in degrees?

    Answer°

  7. Question 7

    What is "the normal" in a ray diagram?

    • A. the reflected ray
    • B. the mirror itself
    • C. any line parallel to the mirror
    • D. a line at 90° to the mirror where the ray hits

  8. Question 8

    A ray of light hits a flat mirror with an angle of incidence of 20°. What is the angle of reflection, in degrees?

    Answer°

  9. Question 9

    A ray of light makes an angle of 65° with the surface of a mirror. What is the angle of reflection, in degrees?

    Answer°

  10. Question 10

    Why can you see your reflection in a mirror but not in a sheet of white paper?

    • A. Paper absorbs all light
    • B. Paper is transparent
    • C. Mirrors make light
    • D. The mirror gives regular (specular) reflection; rough paper scatters light in all directions
