Which of the following electromagnetic waves are listed in the correct order from longest wavelength to shortest wavelength?
a.
infrared, ultraviolet, visible
b.
visible, infrared, ultraviolet
c.
ultraviolet, visible, infrared
d.
infrared, visible, ultraviolet

Answer;

D.

infrared, visible, ultraviolet

Explanation;

Electromagnetic waves are types of waves that do not require a material medium for transmission. An electromagnetic spectrum arranges these electromagnetic waves in the order of increasing frequency and decreasing wavelength.

The spectrum consists of , Radio waves, microwaves, infrared, visible light, UV light, X-rays and Gamma rays; arranged in order of decreasing wavelength and increasing frequency.

Radio waves have the longest wavelength but the lowest frequency, while gamma rays have the lowest wavelength but the largest frequency.

oh it is true if thats what you are asking

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
