Electromagnetic waves do not require material medium for propagation. Radiowaves have the longest wavelength but the least frequency.
Gamma ray has the shortest wavelength but the highest frequency.
The gamma rays and x-rays due to their high frequency, they can disturb the medium they pass through. They have high energy that can cause damage to the matter the come across.

Explanation:
Answer:
<h2>3.7 min</h2>
Explanation:
Step one:
given data
speed = 123m/s
radius of circle= 4330m
Step two:
We need to find the circumference of the circle, it represents the distance traveled
C=2πr
C= 2*3.142*4330
C= 27209.72m
Step three:
We know that velocity= distance/time
time= distance/velocity
time= 27209.72/123
time=221.2 seconds
in minute = 221.2/60
time= 3.7 min
