Chapter 37: Q. 6 (page 1081)

What temperature, in 掳C, is a blackbody whose emission spectrum peaks at (a) 300nmand (b) localid="1649698615260" 3.00渭m?

Short Answer

Expert verified

Required temperatures are:

(a) T=9393.67掳C

(b) T=693.67掳C

Step by step solution

01

Part (a): Step 1: Given information

We have been given the wavelength as:

位=300nm
02

Part (a): Step 2: Calculation

Using Wien's law,

位(nm)=2.9路106(nm路K)T

Here 位is wavelength in nanometers and Tis temperature in Kelvin.

We get the expression for T: T=2.9路106(nm路K)位(nm)

Substituting 位=300nm,

T=2.9路106(nm路K)300T=9666.67KT=9393.67掳C

03

Part (b): Step 1: Given Information

We have been given the wavelength as:

位=3.00渭m

04

Part (b): Step 2: Calculation

Using Wein's Law:

T=2.9路106(nm路K)3000T=966.67KT=693.67掳C
