Question

# The sun emits a light with maximum wavelength $$510nm$$ while another star emits a light with maximum wavelength of $$350nm$$. The ratio of surface temperature of sun and the star will be:

A
0.68
B
2.1
C
1.45
D
0.46

Solution

## The correct option is A $$0.68$$Applying Wein's displacement law,$${\lambda}_{m}T=$$constant$$\cfrac { { \lambda }_{ m }^{ 1 } }{ { \lambda }_{ m }^{ n } } =\cfrac { { T }_{ 2 } }{ { T }_{ 1 } } \Rightarrow \cfrac { 510 }{ 350 } =\cfrac { { T }_{ 2 } }{ { T }_{ 1 } }$$$$\cfrac { { T }_{ 2 } }{ { T }_{ 1 } } =\cfrac { 51 }{ 35 } \Rightarrow \cfrac { { T }_{ 1 } }{ { T }_{ 2 } } =\cfrac { 35 }{ 51 } =0.68$$Physics
