What color will a star be with a surface temperature of 5000 6000 K?
2 answers:
Answer:
The color of a star be with a surface temperature of 5000 6000 K is Yellow.
C is correct option.
Explanation:
According to Wien's displacement law,
The black body radiation will peak at different wavelength due to different temperature.
In mathematical form,
The wavelengths are inversely proportional to the temperature.
According to stellar spectral types
The standard classes
Spectral classes -Temperature - color of stars
M < 3500 K - Red
K - 3500 - 5000 K - Yellow orange
G - 5000 - 6000 K - Yellow
F - 6000 - 7500 K - Yellow white
A - 7500 - 10000 K - white
B - 10000 - 30000 K - Blue white
O - 30000 - 60000 K - Blue
Hence, The color of a star be with a surface temperature of 5000 6000 K is Yellow.

Answer:
45.88297 m
Violet
Explanation:
x = Gap between holes = 5.9 mm
= Wavelength = 527 nm
D = Diameter of eye = 5 mm
L= Distance of observer from holes
From Rayleigh criteria we have the relation
A person could be 45.88297 m from the tile and still resolve the holes
Resolving them better means increasing the distance between the observer and the holes. It can be seen here that the distance is inversely proportional to the wavelength. Violet has a lower wavelength than red so, violet light would resolve the holes better.
