the picture lists light waves from left to right in order of highest to lowest energy. which region of the electromagnetic spectrum has the longest wavelength? a uv b gamma rays c radio waves d visible light
Answer
Answer:
C. Radio Waves
Explanation:
Step1: Recall energy - wavelength relationship
Energy of electromagnetic waves is inversely proportional to wavelength ($E=\frac{hc}{\lambda}$, where $E$ is energy, $h$ is Planck's constant, $c$ is speed of light and $\lambda$ is wavelength).
Step2: Analyze given order
The picture lists waves from highest to lowest energy. Since energy and wavelength are inversely related, the wave with the lowest energy has the longest wavelength. Among the options, radio waves have the lowest energy in the electromagnetic spectrum shown, so they have the longest wavelength.
