Question

q13. (1 point) true / false (circle one): frequencies for uvc light photons are greater than for uva photons.
q14. what are four strategies to reduce uv exposure and harm during high uvi days? (hint: see the cancer council of australia’s sun smart campaign).?
1)
2)
3)
4)

Explanation:

For Q13, in the electromagnetic spectrum, UVC has a shorter wavelength than UVA. Since frequency and wavelength are inversely - related ($c = \lambda
u$, where $c$ is the speed of light, $\lambda$ is wavelength and $
u$ is frequency), UVC photons have higher frequencies. For Q14, common strategies from the Sun Smart campaign to reduce UV exposure include seeking shade, wearing protective clothing, using sunscreen, and wearing a hat.

Answer:

Q13. True
Q14.

1. Seek shade
2. Wear protective clothing
3. Use sunscreen
4. Wear a hat
