An ideal blackbody is an object that

1- absorbs all the energy that strikes it.

2- absorbs most of the energy that strikes it.

3- only absorbs energy at ultraviolet (black light) wavelengths.

4- absorbs a little of the energy that strikes it.

5- absorbs exactly half of the energy that strikes it.

The correct answer is option 1.

Explanation:

An ideal black body is defined as a physical body that absorbs all the radiant energies of falling on it and no energy is reflected back.

All the radiations coming in electromagnetic waves series are absorbed by the ideal black body due to which its surface appears black.

This concept of absorbing of energy is used to study radiation phenomena.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
