Answer:
please the answer below
Explanation:
A general electromagnetic plane wave, traveling in the x direction, can be expressed in the form:
(1)
1.
a. amplitudes
from (1) we can observe that E_0 and B_0 are the amplitudes.
2. frequency
3.
By replacing (1) we obtain:
![\vec{E}=E_0e^{-i(k(0)-\omega t)}\hat{j}=E_0[cos\omega t+sin\omega t]\hat{j}](https://tex.z-dn.net/?f=%5Cvec%7BE%7D%3DE_0e%5E%7B-i%28k%280%29-%5Comega%20t%29%7D%5Chat%7Bj%7D%3DE_0%5Bcos%5Comega%20t%2Bsin%5Comega%20t%5D%5Chat%7Bj%7D)
4.
the wave respond to the followinf physical variables: amplitude, frequency, time and position, as we can see in (1).
hope this helps!!
How hot or cold something is
How much heat is absent (measuring the absence if heat)
(Fun fact- there is no cold just absence of heat
40% of the Earth's surface is covered by continental crust.
