What is the temperature of a star whose maximum light is emitted at a wavelength of 290 nm?

Temperature, T = 10000 K

Explanation:

It is given that,

Wavelength,

We need to find the temperature of a star whose maximum light is emitted at this wavelength. It can be calculated using Wein's displacement law as :

T = 10000 K

So, the temperature of a star is 10000 K. Hence, this is the required solution.

what is the question because that is not a question.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
