Question

2 multiple choice 1 point visible light is the part of the electromagnetic spectrum that we can see. photons of which color have the lowest energy and frequency? increasing energy increasing wavelength 0.0001 nm 0.01 nm 10 nm 1000 nm 0.01 cm 1 cm 1 m 100 m gamma rays x - rays ultra - violet infrared radio waves radar tv fm am visible light 400 nm 500 nm 600 nm 700 nm red yellow violet green

Explanation:

In the visible - light spectrum, red light has the longest wavelength. According to the relationship $E = h
u=\frac{hc}{\lambda}$ (where $E$ is energy, $h$ is Planck's constant, $
u$ is frequency, $c$ is the speed of light, and $\lambda$ is wavelength), longer wavelength means lower energy and frequency.

Answer:

A. Red
