Sun$-T_1$ , tungsten filament $-T_2$ , welding arc $-T_3$
Sun$-T_2$ , tungsten filament $-T_1$ , welding arc $-T_3$
Sun$-T_3$ , tungsten filament $-T_1$ , welding arc $-T_2$
Sun$-T_1$ , tungsten filament $-T_3$ , welding arc $-T_2$
Following graph shows the correct variation in intensity of heat radiations by black body and frequency at a fixed temperature
If wavelengths of maximum intensity of radiations emitted by the sun and the moon are $0.5 \times {10^{ - 6}}m$ and ${10^{ - 4}}m$ respectively, the ratio of their temperatures is
A black body at a temperature of $1640\,\,K$ has the wavelength corresponding to maximum emission equal to $1.75 \,\,\mu m.$ Assuming the moon to be a perfectly black body, the temperature of the moon, if the wavelength corresponding to maximum emission is $14.35\,\,\mu m$ is.......$K$
The intensity of radiation emitted by the sun has its maximum value at a wavelength of $510\;nm$ and that emitted by the north star has the maximum value at $350\;nm$. If these stars behave like black bodies, then the ratio of the surface temperature of the sun and north star is
The distribution of relative intensity $I (\lambda)$ of blackbody radiation from a solid object versus the wavelength $\lambda$ is shown in the figure. If the Wien displacement law onstant is $2.9 × 10^{-3}\ mK$, what is the approximate temperature of the object ....... $K$
