Answer:It is not affected by the change in media.</h2>
Explanation:
Transverse waves are those waves where the medium particles vibrate perpendicular to the direction of propagation.
Transverse waves do not require any medium.
They travel with same speed in any medium.
Electromagnetic waves are transverse waves where the medium particles vibrate perpendicular to the direction of propagation.
So,their speed is same in any medium.
100m so you will subtract 100m from 200m. and you will get your answer 200m-100m=100m
