In a completely inelastic collision, the two objects stick together after the collision.
So, the temperature of a wave that has a wavelength of 5 m is
<h3>Introduction</h3>
Hi ! Here, I will help you to explain about The relationship between temperature and electromagnetic wavelength uses the principle of Wien's Constant. According to Wien, <u>if we multiply temperature with the electromagnetic wavelengths will always got the same number (constant)</u>. Therefore, The relationship is expressed in this equation :
With the following condition :
- C = Wien's constant ≈
- = wave at its longest point (m)
- T = absolute temperature (K)
<h3>Problem Solving</h3>
We know that :
- C = Wien's constant ≈
- = wave at its longest point = 5 m
What was asked :
- T = absolute temperature = ... K
Step by step :
<h3>Conclusion :</h3>
So, the temperature of a wave that has a wavelength of 5 m is
The answer is C, because there are only so many elements therefor you can have only so many compounds.
