Question

Match the Columns :
Column 'A'
Column B
The wavelength of red light
(a)
(6)
(c)
600 nm
700 nm
500 nm​

Answer 1

Answer:

700nm is wavelength of red light

Answer 2

The wavelength of dark red light is 700 nm.

Option (b) is correct.

Explanation:

• The wavelength of visible light ranges from 400 - 700 nm or 4.00 x 10^-7 and 4.00 x 10^-7 m.
• This rage covers infrared light which has longer wavelength and infrared which has shorter wavelength.
• Light is made up to different colors having different wavelengths.
• Thus the wavelength of dark red light is 700 nm.
• The wavelength increases the frequency decreases and vice versa.
