Hint: Light rays are also identified as visible light, electromagnetic radiation that the human eye can recognize. The electromagnetic spectrum is vast, varying from low-energy radio waves with wavelengths estimated in meters to gamma rays with high energy. Light cannot move through opaque objects because they reflect or absorb all light.
Complete step-by-step solution:
Light, also identified as visible light, is electromagnetic radiation within the electromagnetic spectrum that the human eye can see. Visible light having wavelengths in the $400 – 700 nm$ scale, which occupies between infrared and ultraviolet. Light is electromagnetic radiation that displays the characteristics of both waves and particles. Light is a kind of energy. Light also retains the Earth's warmth. Light lives in tiny energy packets termed photons. Each wave possesses a wavelength or frequency. The human eye perceives each wavelength as a various colour. Rainbows display the whole spectrum of light. Other colours except red, orange, yellow, green, blue, indigo, and violet can be viewed only with unique cameras.
There are some characteristics of light: - Light radiation moves at a speed of $3 \times 10^{8} m s^{-1}$ in a vacuum. The speed of light is equal for all electromagnetic waves. The spectrum is a continuous description of all electromagnetic waves formed by frequency and wavelength. Visible light includes only a tiny portion of the spectrum. The brightness of light drops as the square of the distance from the source rises. Transparent objects permit light to travel in vertical lines through them. Objects can be transparent to specific colours or frequencies of light while being dark to others. Ordinary glass is clear to visible light but dull to UV and IR light. As light crosses through translucent substances, it spreads in all directions. Visible light can move through our atmosphere.
The phenomenon by which an electromagnetic wave transports energy from one location to another is mentioned as light propagation. When light moves between borders from one medium to another, three significant processes happen: transmission, reflection, and refraction.
Note: Every light colour has various wavelengths. The smaller the wavelength, the higher energy the light has—the velocity at which light travels is independent of its energy. Going through partly transparent objects can slow light down by a minimal amount. White light is composed of many various colours of light combined. When white light reflects through a prism, it divides up into several colours, becoming a spectrum. The spectrum comprises all of the wavelengths of light that we can perceive. Red light has the largest wavelength, and violet light has the lowest.
