Sunspot Colors. If a sunspot has a temperature of 4200 K, what is the peak wavelength in units of nm using Wien's law(2.90x106 /T)?
A star has a surface temperature of 4,211 K. What is peak wavelength in nm of the light it emits? Give the answer to two significant figures. Use scientific notation, with one digit to the left and one digit to the right of the decimal point.
Our sun's 5800 K surface temperature gives a peak wavelength in the middle of the visible spectrum. 1. What is the minimum surface temperature for a star whose emission peaks at some wavelength less than 400 nm− that is, in the ultraviolet?
What is the peak wavelength of light coming from a star with a temperature of 7,750 K? (Submit your answer in nanometers. Remember 1nm = 10-9 m)
A cavity is maintained at a temperature of 2650 K: a) At what wavelength is the peak of the radiated energy? b) At what rate does the energy escape from a 1.00 mm hole in the walls of the cavity?
What is the temperature If the peak of a blackbody spectrum is at 17.0 m? What is the wavelength at the peak of a blackbody spectrum if the body is at a temperature of 1700 K? About 0.1ev is required to break a "hydrogen bond" in a protein molecule. Calculate the minimum frequency and maximum wavelength of a photon that can be accomplish this minimum frequency
According to Wein’s Law, The peak wavelength of radiation emitted is determined by the temperature of the emitter according to the following equation. λmax=2900/Twhere T is the temperature of the emitter in degrees Kelvin (water freezes at 273 degrees K, 0 degrees Celsius and 32 degrees Fahrenheit). NASA’s Cassini space probe has made several fly-bys of Saturn’s moon Titan, the only moon with an atmosphere. Here is your problem. Given that Earth’s average temperature is 15 degrees Celsius and Titan’s...
The peak wavelength in the cosmic microwave background is 1mm. This corresponds to a temperature of about 3K. To what frequency would you need to tune a radio receiver to receive a microwave signal with this wavelength
