How does quantum theory explain blackbody radiators? O A. As the radiator is heated, it can have only certain specific temperature values. B. Raising the temperature results in the radiator giving off photons of high-energy ultraviolet light. C. Raising the temperature of the radiator causes more photons of a few possible energies to be emitted. D. As heat is added, the radiator emits photons across a wide range of visible-light frequencies SU​

B. Raising the temperature results in the radiator giving off photons of high-energy ultraviolet light

Explanation:

Quantum theory explains the nature of matter and its behavior on the atomic level. It should be noted that at higher temperature, radiation is emitted by the blackbody at higher intensity and frequency.

Raising the temperature results in the radiator giving off photons of high-energy ultraviolet light. It should also be noted that there isn't a limit to the temperature of the blackbody.

The correct option is B.

Explanation:

The CORRECT answer is C. Raising the temperature of the radiator causes more photons of a few possible energies to be emitted.

Quantum theory suggests that photons can only exist in a few possible energy states.

Energy coming off a radiator is usually in the infra-red light; not ultraviolet. So B is not the right answer.

it would be kevlar ^^

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
