The wavelength of maximum intensity
Webwavelength of maximum emission of any body is inversely proportional to its absolute temperature (measured in Kelvin). As a result, as the temperature rises, the maximum (peak) of the radiant energy shifts toward the shorter wavelength (higher frequency and energy) end of the spectrum (bluer). This is what the equation looks like: WebThe temperature of star which has maximum energy emission at 400 nm will be. Experimental investigation show that the intensity of solar radiation is maximum for a wavelength 480 nm in the visible region. Estimate the surface temperature of sun. Given Wien's constant b = 2.88×10 −3 m K.

WebA blackbody with this temperature has its peak at approximately 500 nanometers, which is the wavelength of the color yellow. A blackbody that is twice as hot as the sun (about 12000 K) would have the peak of its spectrum occur at about 250 nanometers, which is in the UV part of the spectrum.
WebSep 12, 2024 · The wavelength can thus be found using Equation 3.3.2 for constructive interference. Solution Solving Equation 3.3.2 for the wavelength λ gives λ = d sin θ m. Substituting known values yields λ = ( 0.0100 m m) ( sin 10.95 o) 3 = 6.33 × 10 − 4 m m = 633 n m. Significance WebWe can rearrange this equation to solve for the wavelength of the light: λ θ = w × θ To find θ, we can use the small angle approximation: θ ≈ y / L where y is half the distance between the positions of zero intensity (i.e., y = 1.20 mm), and L is the distance from the slit to the screen (i.e., L = 1.35 m).
