What is photothermal energy?
phtothermal effect is low power wavelength and using then low temperature & velocity.
How does long wavelength radiation contribute to the greenhouse effect?
The trapping by the greenhouse gases of the long wavelength radiation (infrared) leads to more heating and a higher resultant temperature.
Is the color of star an effect of its temperature?
Yes. The apparent colour of a star is related to the peak wavelength of the light it emits. According to Wien's displacement law (look it up in Wikipedia) the peak wavelength is inversely proportional to the temperature. The higher the temperature, the shorter the peak wavelength. Wavelength decreases as one moves from red to blue in the visible spectrum, so a red star is cooler than a blue one.
Is there any effect of wavelength on refractive index?
The refractive index depends on the wavelength of the radiation. Traditionally the sodium line NaD20 (589,3 nm) is used for measurements (20 is the temperature on the Celsius scale).
What is important about the peak wavelength of a thermal radiation spectrum?
The peak wavelength, is connected to the temperature of the objects. we have short peak wavelength when the temperature is high.
How measure the sun temperature?
Use a spectrometer to measure the wavelength of the light. There is a direct, but inverse correlation of the wavelength to the temperature.
What effect if any does increasing the speed of the plunger have on the wavelength of the waves?
It will shorten the wavelength.
What effect if any does the increasing the speed of the plunger have on the wavelength of the wave?
It will shorten the wavelength.
What is de-Broglie wavelength of an atom at absolute temperature T K?
de Broglie wavelength depends only on the mass and speed of the particle and not on the temperature
Does refractionand reflection effect the wavelength of sound?
No.
How does the amount energy affect the size of the wavelength?
Energy does not effect WAVELENGTH, it effects the AMPLITUDE of the Wave.
what is the colour temperature and wavelength of incandescent lamp?
An incandescent lamp's light has a color temperature between '2700 to 3300 K". Such a temperature approximates an ideal black body radiator, and it could have an effect of "warm". If a neodymium coating is used, the color ranges from yellow to red. After a period of use, the color turns into white and then to blue. Blue and black colors are at the end of the visible wavelength.
