Circle the best answer, or write your answer on the line.

  1. Planck's constant is 4.135667696 × 10⁻¹⁵ eV·s. What energy does one photon of orange light at 5 × 10¹⁴ Hz carry, to the nearest hundredth, Ari?

  2. Planck's constant is 4.135667696 × 10⁻¹⁵ eV·s. What energy does one photon of red light at 4.3 × 10¹⁴ Hz carry, to the nearest hundredth, Esme?

  4. In the wave diagram, which bands are on the ionizing side of the line, Jun?

    • Infrared and visible light
    • Radio waves and microwaves
    • X-rays and gamma rays

  5. In the wave diagram, what can ionizing radiation do that the other bands can't, Kira?

    Use the picture in question 3.

    • Travel at the speed of light
    • Knock electrons out of atoms
    • Warm things up

  6. In the wave diagram, which side of the line are microwaves on, Luz?

    Use the picture in question 3.

    • The ionizing side, since microwaves ionize
    • The non-ionizing side
    • Right on the line

  7. What do microwaves do when food absorbs them, Milo?

    • They make it glow
    • They make it radioactive
    • They warm it

  8. A heat lamp shines infrared on a plate of food. What does the absorbed infrared do, Noah?

    • It cools the food
    • It ionizes the food
    • It warms the food

  9. What do green plants do with the visible light their leaves absorb, Pia?

    • Turn it into radio waves
    • Use its energy to make food
    • Store it as X-rays

  10. Which part of sunlight causes sunburn, Ren?

    • Ultraviolet
    • Visible light
    • Radio waves

  11. What does sunscreen do, Tala?

    • Blocks the sun's visible light
    • Blocks much of the sun's ultraviolet
    • Turns ultraviolet into X-rays

About this worksheet

What different kinds of radiation do when absorbed. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can find the energy of one photon, E = hf, in eV, and say that it rises with frequency.
  • I can place the ionizing line. The EPA lists radio waves, microwaves and visible light as non-ionizing, and X-rays and gamma rays as ionizing. I can explain that ionizing depends on each photon's energy, not on how bright a beam is.
  • I can describe what absorption does: microwaves and infrared warm (ΔT = Pt ÷ mc), visible light powers plants, and ultraviolet can cause sunburn, which sunscreen helps block.
  • I can compare imaging doses with natural background (a chest X-ray is about 10 days' worth) and check short published-style claims against these facts.

Standard: HS-PS4-4

Words to know

photon: One packet of electromagnetic energy

electron volt (eV): A tiny energy unit for single photons

ionizing: Able to knock electrons out of atoms (EPA)

non-ionizing: Not able to remove electrons; can warm or move molecules

millisievert (mSv): A unit for comparing radiation doses

Common mistakes

Your child divided. A photon's energy is Planck's constant × frequency: E = hf.

Your child left out the water's mass. Temperature rise = energy ÷ (mass × specific heat).

Your child divided the small dose by the large one. To count how many small doses fit in a large one, divide large by small.

Questions parents ask

What is the most common mistake with what different kinds of radiation do when absorbed?

Your child divided. A photon's energy is Planck's constant × frequency: E = hf.
