- 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 energy
- Hence, vibrating atoms radiate energy
- Hotter atoms vibrate more quickly so do more accelerating, so they emit more radiation!
What else can I help you with?
Do all objects radiate?
no...
Do all objects give off thermal radiation?
yes every object gives out thermal radiation
What are the factors does the heat emitted by a hot body depend?
The heat emitted by a hot body depends on its temperature, surface area, and emissivity. The Stefan-Boltzmann law states that the total amount of heat radiation emitted by a body is directly proportional to the fourth power of its absolute temperature.
Is absorbed radiation re emitted as energy?
Yes, absorbed radiation can be re-emitted as energy in the form of electromagnetic radiation or heat. This phenomenon is known as re-emission or re-radiation. The amount and wavelength of the re-emitted radiation depend on the properties of the absorbing material.
How does infra red radiation depend on the temperature?
Infrared radiation is directly proportional to an object's temperature, according to Planck's law. As temperature increases, the intensity of infrared radiation emitted by an object also increases. This relationship is described by the Stefan-Boltzmann law.

What degree do you tan at?
That doesn't depend on the temperature, but on the amount of UV radiation you receive.

Infrared radiation is directly proportional to an object's temperature, according to Planck's law. As temperature increases, the intensity of infrared radiation emitted by an object also increases. This relationship is described by the Stefan-Boltzmann law.
Why do all objects emit?
All objects emit thermal radiation because they have a temperature above absolute zero. This thermal radiation is a form of electromagnetic radiation that includes visible light, infrared, and ultraviolet rays. The intensity and wavelengths of the radiation emitted depend on the temperature of the object.
Different types of radiation that stars emit?
Stars emit various types of radiation, including visible light, ultraviolet light, infrared radiation, and X-rays. Additionally, stars also emit radio waves and gamma rays. The type and amount of radiation emitted by a star depend on its temperature, mass, and stage of evolution.
What are waves given off by hot glowing objects?
Waves given off by hot glowing objects are called electromagnetic radiation, which includes visible light, infrared radiation, and ultraviolet radiation. The specific wavelengths emitted depend on the temperature of the object - the hotter the object, the shorter the wavelengths emitted.
Do all objects at any temperature emit radiant energy?
All object at any temperature irradiate radiation, yet, net total energy may be in minus.In example, earth do reflect and irradiate energy to the sun but in total we recieved energy from the sun at approx 1400 W/m2
What are the characteristics and implications of blackbody radiation, and how do examples of blackbody radiation help us understand the concept better?
Blackbody radiation refers to the electromagnetic radiation emitted by a perfect absorber and emitter of energy. The characteristics of blackbody radiation include its continuous spectrum and dependence on temperature, as described by Planck's law. This concept has implications in understanding the thermal radiation emitted by objects and the energy transfer in various systems. Examples of blackbody radiation, such as the radiation emitted by stars or heated objects, help us understand the concept better by demonstrating how the intensity and wavelength distribution of the radiation depend on the temperature of the object. By studying these examples, we can gain insights into the behavior of thermal radiation and its role in various physical phenomena.
What does a hot hydrogen gas emit?
Hot gases of any kind emit electromagnetic radiation.
