Question

arrange the following types of uv radiation from least to most energetic. uv - b, uv - c, uv - a uv - a, uv - b, uv - c uv - c, uv - b, uv - a uv - c, uv - a, uv - b

Explanation:

UV - A has the longest wavelength among the three, so it has the least energy. UV - B has a shorter wavelength than UV - A but longer than UV - C. UV - C has the shortest wavelength and thus the most energy. The energy of electromagnetic radiation is inversely proportional to its wavelength ($E=\frac{hc}{\lambda}$, where $E$ is energy, $h$ is Planck's constant, $c$ is the speed of light, and $\lambda$ is wavelength).

Answer:

UV - A, UV - B, UV - C
