Answer:
The correct option is (A).
Explanation:
When the temperature of the hot solid object increases then the radiation which emits from it gets shifted to smaller wavelength or higher frequencies. The hot appears red color.
The total energy emitted of a hot solid object is directly proportional to the fourth power of the temperature of the black body.
For example, when we switch on the light bulb, initially the radiation of the bulb appears dimmer. Then, it will become brighter. Then, it will turn yellow and then it becomes even white.
The color of the light emitted by a hot solid object depends on the temperature of the object.
Therefore, the correct option is (A).
Answer:

Explanation:
Answer:
According,to the law of conservation of energy,the amount of energy in a closed system always stay constant. ... So,the amount of work output and other transformed energy is equal to the amount of energy inputs. • In this way,the conservation of energy is fulfilled by the machines.
Alike - both part of the light spectrum, cannot be seen with the naked eye
Different - IR is less energetic than UV, UV has a shorter wavelength than IR
IR - infrared
UV - ultraviolet
