Wien's Law, also known as Wien's Displacement Law, asserts that black body radiation has various temperature maxima at different wavelengths and that the temperatures are inversely proportional.
Wien's Law is depicted in the following way: λmax = b/T
Here is a representation of Wien's Law with frequency.
fmax = k * T
Question 1: The wavelength of maximal solar radiation has been calculated to be around 0.52 μm. What is the temperature of the sun's surface?
Consider the problem, we have
Maximum Wavelength = 4.75 m = 4.75 x 10-7 m
b=2.9 x 10-3 m K
The formula for Wien's Displacement Law is wavelength = b/Temperature.
T = 2.9 x 10-3/4.75 x 10-7
T= 2.9 x 10-3/4.75 x 10-7
T= 2.9 x 10
As a result, the sun's surface temperature is 6100°K.
1. What applications does Wien's displacement law have?
Wien's law is used to determine the temperatures of hot radiant objects such as stars and the sun, as well as any radiant object whose temperature is much higher than that of its surroundings. The sun's temperature and incandescent bulb light are two examples of Wien's displacement rule in action.
2. What is Wien's constant's value?
The numerical constant utilised in the peak frequency formula is k = 5.8789232*1010 Hz/K, while the Wien's law constant value is b = 2.8977719 mm*K.
3. What is the formula for calculating an object's body temperature using Wien's law?
The temperature may be calculated using two simple calculations using Wien's displacement law. The peak frequency is used in one case, whereas the peak wavelength is used in the other.
4. The human body has a temperature of 43 degrees Celsius. What wavelength has the highest intensity of radiation released by the human body?
