Question

Within the visible spectrum, red light has.
a the shortest wavelength and the lowest frequency
b the longest wavelength and the lowest frequency
c the longest wavelength and the highest frequency
d the shortest wavelength and the highest frequency

Answer 1

Answer:

B

Explanation:

It would be B. Think of frequency as the amount of humps in the waves. If it has less ups and down/longer spaces, it would have low frequency.  The wavelength of red is about 600-740.

Answer 2

It’s B. Red light has longer waves, with wavelengths around 620 to 750 nm. Infrared and radio waves are at the long wavelength side while ultraviolet (UV), x-rays and gamma rays lie at the short wavelength side of the electromagnetic spectrum. Radiation with wavelengths shorter than 400 nm cannot be sensed by the eye. Light with wavelength longer than 700 nanometers is also invisible.
