Answer:
t = 160 minutes
Explanation:
Given that,
Distance of Uranus from Sun is
We need to find the time taken by the light to go from sun to Uranus if the velocity of light is constant in free space and it is equal to c.
So,
Since, 1 minute = 60 seconds
t = 160 minutes
So, 160 minutes is taken by the light.
First of all, the question is vague as you haven't mentioned the medium of propagation of the wave, which is extremely crucial.
For example light travels at <span>299,792</span> km/second in vacuum, but in certain semiconductors, it travels as slow as 9 km/second. Sound, ocean and seismic waves don't exist in vacuum at all.
If you mean the maximum possible speed any of these options can attain in any medium of choice for the different options, then the answer would be
b. radio waves, which travel exactly at the speed of light in vacuum (299,792 km/second) and with an almost similar(slightly less) speed in air. (Radio waves are nothing but electromagnetic waves with low frequency)
Answer:
the answer is equal to yes
