What objects will emit energy in the universe?
Any object in the universe with a temperature above absolute zero
Atoms emit energy as light when?
Atoms emit energy as light when electrons move to a lower energy level
What is a self luminous object that shines through the release of energy?
the objects which emit light of their own........example:sun,burning candle etc....,
Does a hot object emit photons with a longer wavelength than cold objects?
nopes, shorter. hot object will emit photons at high frequency (=blue flame for example, short WL) and cold object will emit photons at lower frequency (=IR for example which our bodies emit, long WL)
How is heat lost in a vacuum flask?
By radiation. When an object is hot, it's electrons get energy so they go to a higher energy state, when they return to their ground state, they emit that energy in form of electromagnetic radiation (usually infrared), also unless the object is floating, it'll transfer heat to the objects that touch it.
An object is warmer than its surroundings it will?
Release its heat energy until the object (system) and the surroundings are the same temperature.
What types of objects emit of infrared raditation?
Any object emits infrared radiation. The hotter the object, the more infrared is emitted.
What type of radiator of energy is an object that is a good absorber of radiation?
An object that absorbs heat well will also emit heat well. The object will emit heat until equilibrium is reached with its surroundings.
What objects will emit energy in the universe?
Any object in the universe with a temperature above absolute zero
What type of energy does an element need to absorb to emit light?
Many different types of energy can do this. Heat will cause anything to emit blackbody radiation and if there is enough heat the blackbody radiation will overlap the visible light spectrum and the object will be incandescent. To emit light as a narrow spectral line requires raising electrons in the element to higher energy orbitals and allowing them to fall back, emitting photons. The type of energy that can do this can be of many sorts: light, chemical, electrical, etc.
Who was the first scientist to propose that an object could emit only certain amounts of energy?
Niels Bohr
How can you measure the surface temperature of the sun?
Indirectly, by analyzing the light given off by the Sun. Typically, a hotter object will emit electromagnetic waves of higher-energy - on average, because such an object will emit a mix of many electromagnetic waves.
Atoms emit energy as light when?
Atoms emit energy as light when electrons move to a lower energy level
What is a self luminous object that shines through the release of energy?
the objects which emit light of their own........example:sun,burning candle etc....,
What type of energy does sun emit?
solar energy.
What kind of energy waves do black holes emit?
Black holes emit a great deal of x-ray energy.
Does a hot object emit photons with a longer wavelength than cold objects?
nopes, shorter. hot object will emit photons at high frequency (=blue flame for example, short WL) and cold object will emit photons at lower frequency (=IR for example which our bodies emit, long WL)
