Correct option is D
The correct answer is: (d), D, B, A, C
Gamma
Ultraviolet
Infrared
Microwave
Gamma Gamma rays have the shortest wavelength among the options provided, making them the highest in energy and frequency.
Ultraviolet The Sun is the main source of ultraviolet radiation. It causes skin tanning and burns. Hot materials that are in space also emit UV radiation.
Infrared It is used widely in night vision goggles. These devices can read and capture the infrared light emitted by our skin and objects with heat. In space, infrared light helps to map interstellar dust.
Infrared radiation, also commonly referred to as infrared light, is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves. It is invisible to the human eye but can be felt as heat.
Microwave This type of radiation is found in microwaves and helps in cooking at home/office. It is also used by astronomers to determine and understand the structure of nearby galaxies and stars.
Information booster
The electromagnetic spectrum comprises all electromagnetic waves, organized based on their frequency or wavelength. It serves as a fundamental framework for comprehending the transmission of energy through space. This spectrum plays a pivotal role across numerous scientific domains, facilitating investigations into atomic and molecular structures, celestial events, and diverse communication and imaging technologies.
These waves vary greatly in their properties and are categorized into different types:
Radio Waves: Radio waves are generated by charged particles undergoing acceleration, such as electrons in an antenna. When these particles accelerate, they create oscillating electric and magnetic fields, which propagate outward at the speed of light.
Microwaves Microwaves are generated using electronic devices called magnetrons. They are absorbed by materials containing polar molecules, especially water. When absorbed, the energy of the microwaves causes the polar molecules to vibrate, producing thermal energy (heat). Cosmic microwave background radiation fills the entire universe and is a clue to the Big Bang
Infrared Waves Infrared waves are invisible to the human eye but can be felt as heat. All objects emit infrared radiation as a function of their temperature. The hotter an object is, the more infrared radiation it emits.
Visible Light The visible spectrum encompasses all the colors perceivable by the human eye, from violet (shortest wavelength) to red (longest wavelength). The colors include violet, indigo, blue, green, yellow, orange, and red. exhibits both wave-like and particle-like properties
Ultraviolet Lights Ultraviolet (UV) light is electromagnetic radiation that lies beyond the visible spectrum at its violet end. UV radiation influences atmospheric chemistry, particularly in the formation and depletion of ozone
X-Rays X-rays are a form of electromagnetic radiation which are naturally emitted by cosmic phenomena such as black holes, neutron stars, and supernova remnants. They can also be produced in labs using X-ray tubes and Synchrotron.
Gamma Rays Gamma rays represent the highest-energy end of the electromagnetic spectrum. They are often produced by the decay of radioactive nuclei. This process, known as gamma decay, involves the emission of a gamma photon from an excited nucleus.
