Answer 1

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:

$c=3.0\cdot 10^8 m/s$

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

Answer 2

The correct statements for the respective options are:

• The shortest wavelength of visible light is violet light.
• The energy that can be felt as heat but not seen is infrared rays.
• Short, invisible rays that can cause eye damage is ultraviolet rays.
• The visible light with the longest wavelength is the red light.

Electromagnetic radiations are the energy waves that constitute electrical as well as magnetic fields.

The electromagnetic spectrum is the arrangement of these waves in the increasing or decreasing order of wavelength and frequency.

The waves are:

• Gamma rays.
• X-rays
• Ultraviolet rays
• Visible light
• Infrared
• Microwaves, and
• Radiowaves

Out of these electromagnetic waves, only visible light is visible to human eyes and the others are not.

The shortest wavelength of visible light is of violet color. The violet light has the highest frequency in visible light and the shortest wavelength.

The energy that can be felt as heat but not seen is the infrared wave.

Ultraviolet is an invisible ray that can cause eye damage.

The visible light which has the longest wavelength is the red light.

Therefore, the correct answers for the respective options are:

• The shortest wavelength of visible light is violet light.
• The energy that can be felt as heat but not seen is infrared rays.
• Short, invisible rays that can cause eye damage is ultraviolet rays.
• The visible light with the longest wavelength is the red light.
