The ratio of absolute temperatures of two black bodies is 2 : 1. The ratio of their maximum radiation intensities will be

Answer»

` 1:32`
` 32:1 `
` 8:1`
` 16:1`

Solution : MAXIMUM radiation INTENSITY `PROP (T)^5` This is Wien.s energy distribution law
`(E_(m_1))/(E_(m_2))=((T_1)/(T_2))^5=((2)/(1))^5= 32/1`
