Question

1. interpret scientific illustrations use figure 5 and your knowledge of electromagnetic radiation to match the numbered items with the lettered items. the numbered items may be used more than once or not at all. a. longest wavelength 1. gamma ray b. highest frequency 2. infrared wave c. greatest energy 3. radio waves

Explanation:

• For a. longest wavelength: Radio waves have the longest wavelength among the given options. In the electromagnetic spectrum, radio waves are at the end with the largest wavelength values.
• For b. highest frequency: Gamma rays have the highest frequency. Frequency and wavelength are inversely related ($c = \lambda

u$, where $c$ is the speed of light, $\lambda$ is wavelength, and $
u$ is frequency). Since gamma rays have a very short wavelength, they have a high frequency.

• For c. greatest energy: Energy of a photon is given by $E = h

u$ (where $h$ is Planck's constant and $
u$ is frequency). Gamma rays, with their high frequency, have the greatest energy among the given options.

Answer:

a. 3. radio waves
b. 1. gamma ray
c. 1. gamma ray
