What type of radiation does earth's surface radiate to cool down?
The Earth's surface radiates thermal infrared radiation to cool down. This energy is absorbed from the sun during the day and then emitted as heat at night to balance the energy received.
What type of radiation is trapped on earth's surface by the greenhouse effect?
terestrial
Do hotter stars radiate more energy at higher frequencies?
Yes, hotter stars radiate more energy overall, with a greater proportion emitted at higher frequencies. This is due to the relationship between temperature and the peak wavelength of light emitted, known as Wien's Law. As a star's temperature increases, the peak wavelength shifts towards shorter, higher-energy wavelengths.
Two planets that radiate away more energy than they receive from the sun are?
Two examples of planets that radiate away more energy than they receive from the sun are Jupiter and Saturn. These gas giants emit more thermal energy due to their internal heat sources, such as radiation leftover from their formation and gravitational compression.
If the inner accretion disk around a black hole has a temperature of 1000000 K at what wavelength will it radiate the most energy?
For a thermal radiation source, the peak of the blackbody radiation curve is at a photon energy 2.8 times the temperature in electron-volts. The temperature in electron-volts is 1/11,600 times the temperature in Kelvin. Use E = hv to convert from the photon energy (E) to photon frequency, using Plank's constant h. Use v = c/(lambda) to convert from the photon frequency to the wavelength. The result: these hot plasmas radiate X-rays, and the peak wavelength is about 50 Angstroms, i.e. 5 nm.
What is radiation balance and how will you explain it?
Radiation balance refers to the equilibrium between incoming solar radiation absorbed by the Earth and outgoing thermal radiation emitted back into space. The Earth's surface and atmosphere absorb sunlight, which warms the planet, and re-radiate heat energy back into space. This balance is crucial for maintaining Earth's temperature and climate.
Do all objects radiate?
no...
Why not earth radiate light?
Earth does radiate light in the form of thermal radiation, which is emitted as heat energy. This radiation is typically in the infrared range and is a result of the Earth's surface absorbing sunlight and then re-emitting it as heat.
What objects can radiate energy?
Objects that can radiate energy include stars, light bulbs, heated coils, and the Earth's surface. The type of radiation (such as heat, light, or electromagnetic waves) emitted by an object depends on its temperature and composition.
What kind of objects better radiate in shorter wavelengths?
Objects with higher temperatures tend to radiate more strongly in shorter wavelengths. This is known as Wien's displacement law, which states that the peak wavelength of radiation emitted by an object is inversely proportional to its temperature. Therefore, objects with higher temperatures will emit more of their radiation in shorter wavelengths.
Why does amount of black body radiation emitted depend on temperature of object?
The hotter an object gets the faster its atoms vibrate.Vibration can be considered as a repeating cycle of accelerating, decelerating and then accelerating back again in the other direction.Accelerating charges radiate energyHence, vibrating atoms radiate energyHotter atoms vibrate more quickly so do more accelerating, so they emit more radiation!
What type of radiation does earth's surface radiate to cool down?
The Earth's surface radiates thermal infrared radiation to cool down. This energy is absorbed from the sun during the day and then emitted as heat at night to balance the energy received.
What is chi-radiation?
Chi radiation is the ability to radiate or push out you chi i every direction.
What is the root word of radiation?
The root word of radiation is the word 'radiate', which means to extend, spread, or move like rays or radii from a center; to emit rays, as of light or heat.
What wavelengths does a high temperature source radiate?
A high temperature source such as the Sun emits radiation across a wide range of wavelengths, from ultraviolet to visible light to infrared. The peak wavelength of radiation emitted by a high temperature source is determined by its temperature according to Wien's displacement law.
What is radiation and how does sweat radiate from skin?
Radiation is energy emitted in the form of waves or particles. When sweat is produced by sweat glands in the skin, it evaporates and releases heat energy from the body through a process called radiation. The heat energy is transferred from the skin to the surrounding environment through the emission of infrared radiation.
Does a refrigerator require radiation?
Yes. A refigerator needs to radiate heat.
