Two stars ' P ' and ' Q ' emit yellow and blue light respectively. The relation between their temperatures ( T _ P . and . T _ Q ) is
Options
- AT _ P = T _ Q
- BT _ P = T _ Q 2
- CT _ P > T _ Q
- DT _ P < T _ Q
Correct answer
D. T _ P < T _ Q
Step-by-step solution
According to wien's law, T= constant T 1 wavelength of blue light is less that than of yellow light. Hence, temperature of Q is greater than temperature of P .
