What else can I help you with?
Is ultraviolet radiation the energy emitted by earth?
No, ultraviolet radiation is not emitted by the Earth itself. Ultraviolet radiation comes from the sun and is a form of electromagnetic radiation with shorter wavelengths than visible light. Earth's atmosphere filters and absorbs some of the incoming ultraviolet radiation before it reaches the surface.
Why is measurement made at right angles to the direction of the incident radiation in luminescence spectroscopy?
In luminescence spectroscopy, measurements are taken at right angles to the direction of the incident radiation to minimize the detection of scattered light and enhance the signal from emitted luminescence. This configuration helps to reduce background noise and improves the signal-to-noise ratio, allowing for more accurate measurements of the emitted light. Additionally, it ensures that the detected signal is primarily due to the sample's luminescence rather than reflections or scattering from the excitation source.
Why light emitted by bulb is not monochromatic?
Light bulbs aim to emulate the light emitted by the Sun, which radiates as a black body at 6000 degrees C. The light is emitted over the entire visible spectrum. Some bulbs produce monochromatic light, sodium street lights for example.
What do you understand by the statement a star is eight light years away from the earth?
The light from a star eight light years away will take eight years to reach Earth.
What is the difference between emitted light and exciting light?
excited light is the light a chemical absorbs raising it from it's ground state to an excited state. Energy is released as heat and as light. Causes flourescence when chemical returns itself to its ground state. emitted light is the light emitted from the absorbing chemical. When this happens a substance(usually an organic) is emitting a light of longer wavelength after absorbing light of a shorter wavelength.
Is there light coming from any planets?
no light is not emitted by any planet but light ,reflected by many planets comes to the earth
What makes it possible to see the Moon from Earth?
to use ur eyes wow really -.-..... Light emitted by the Sun is reflected to Earth by the Moon's surface.
The wavelengths of radiation emitted by Earth are?
Earth emits radiation across a wide range of wavelengths, including infrared, visible light, and some ultraviolet. This radiation is primarily determined by the temperature of Earth's surface and atmosphere.
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.
How does the radiation emitted from the sun differ from the radiation emitted by earth?
The Sun emits a broader spectrum of radiation, including visible light, ultraviolet rays, and infrared radiation, while Earth primarily emits infrared radiation due to its lower temperature. The Sun's radiation is much more intense and has higher energy compared to the radiation emitted by Earth.
What Radiation emitted by a body that absorbed it first?
The radiation emitted by a body that absorbed it first is known as re-emitted or secondary radiation. This occurs when absorbed energy is re-radiated by the object in a different form such as heat or light.
What is the color of light emitted by the sun?
The color of light emitted by the sun is white.
Do starts reflect light?
Yes, stars produce their own light through nuclear fusion in their cores. This light is emitted in various wavelengths, including visible light that we can see from Earth. The intensity and color of the light emitted by stars depend on their temperature and age.
How long would it take for a signal to travel from a star located 100 light years away to reach Earth in Earth years?
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
What process when light is emitted in all directions?
Scattering. The location inside the Earth where an earthquake begins is called the focus.
Four of Jupiters satellites can be seen from Earth using a telescope What makes these satellites visible?
light emitted by the satellites
How long would it take for a signal to travel from Earth to a star located 100 light years away?
It would take 100 years for a signal to travel from Earth to a star located 100 light years away.
