The wavelength of the maximum emitted energy of a body at 700 k is 4.08μm. if the temperature of the body is raised to 1400K. the wavelength of maximum emitted energy will be

The correct option is D 2..04μmλm1T1 = λm2T2⇒λm2 = λm2T1T2 = 4.08×7001400 = 2..04μm

The wavelength of the maximum emitted energy of a body at $700$ k is $4.08 μ m$ . if the temperature of the body is raised to $1400 K$ . the wavelength of maximum emitted energy will be

The correct option is D $2..04 μ m$
$λ_{m_{1}} T_{1}$ = $λ_{m_{2}} T_{2}$

$\Rightarrow λ_{m_{2}}$ = $\frac{λ_{m_{2}} T_{1}}{T_{2}}$ = $4.08 \times \frac{700}{1400}$ = $2..04 μ m$
