Answers
The shortest wavelength of visible light = violet light
Energy that can be felt as heat but not seen = infrared
Short, invisible rays that can cause eye damage = ultraviolet
Visible light with the longest wavelength = red light
Explanation:
Electromagnetic waves are waves consisting of oscillations of the electric and the magnetic field, occurring in a plane perpendicular to the direction of motion the wave.
They are the only type of waves able to travel without a medium, and they are transverse in nature.
All electromagnetic waves travel in a vacuum at the speed of light, which value is:
c=3.0\cdot 10^8 m/sc=3.0⋅10
8
m/s
Electromagnetic waves are classified into 7 different classes, depending on their wavelength/frequency, and they have different properties. From shortest to longest wavelength (and from highest to lowest frequency), they are:
Gamma rays
X rays
Ultraviolet
Visible light
Infrared radiation
Microwaves
Radio waves
Moreover, the visible light of the spectrum is further divided into different colors, according to how our eye perceive them; from shortest to longest wavelength:
violet
blue
green
yellow
orange
red
Therefore, we have:
The shortest wavelength of visible light is violet light, which has wavelength between 380 and 450 nm
The longest wavelength of visible light is red light, which has wavelenght between 620 and 750 nm
Infrared radiation is a type of radiation that is felt as heat by our body, however it cannot be seen because it falls outside the spectrum of visible light
Ultraviolet radiation is also invisible to human eye; it has shorter wavelength than visible light and therefore it has more frequency (and more energy), therefore it can cause damage, especially to the eye
