1- Red color has the longest wavelength. Red light belongs to the visible spectrum of light and the wavelength of visible spectrum ranges from 700nm to 400nm, from red to violet respectively.
2- Gamma rays, x-rays, visible light and radio waves are all types of electromagnetic radiations. Electromagnetic radiations contain visible light, radio waves, gamma rays and x-rays. These radiations has varied electric and magnetic fields.
3- The fact that light can exert a pressure on matter suggests that it is made up of photons.
• In the spectrum, the light red color has the maximum wavelength.
• The different types of electromagnetic radiations are x-rays, radio waves, gamma rays and visible light.
• Light is made up of photons; therefore, it exerts pressure on matter.
Further Explanation:
The light spectrum of visible light is a part of the electromagnetic spectrum that can become visible through the eye of the human. The different array of wavelengths is referred to as visible light. The human can easily visualize wavelength around from 390-690 nanometers. The different kinds of EM radiation that are the part of the electromagnetic spectrum:
• Gamma rays
• Microwaves
• Infrared light
• Ultraviolet light
• X-rays
• Radio waves
• Visible light
All the electromagnetic radiations are light; an individual can only visualize the smart part of these radiations. The visualize part of electromagnetic radiation is referred to as visible light. Cone cells present in eyes help in visualizing the wavelength of the spectrum. When the spectrum of light is passing through the prism, then they differentiate into a different color of the rainbow. This is because each color consists of a different wavelength. So, violet color has the lowest wavelength and red color has the maximum wavelength.
Photons are the energy particles and they travel in the form of light. The energy of a photon particle depends on radiation frequency. Photons are absorbed when moving from lower energy to higher energy levels and vice versa.
