Four of the wavelengths of the balmer series occur in the visible spectrum (656 nm, 486 nm, 434 nm, and 410 nm). in which region of the electromagnetic spectrum does the fifth line, with a wavelength of 397 nm, occur?

a) x rays
b) gamma rays
c) radio waves
d) ultraviolet
e) visible light
f) infrared
g) microwaves

radio waves, microwaves, infrared waves.

Explanation:

Electromagnetic spectrum increases in wavelength and decreases with frequency in the following order

Gamma ray, X ray, Ultraviolet rays, Visible light, Infrared rays, Radio waves.

Since 397nm is greater than the value of visible spectrum, this shows that radio waves, microwaves and infrared wave falls in the spectrums of the wavelength value.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
