Answer:
A large amount of heat and pressure
To calculate this we will use the light equation:

λ

We have Frequency

.
We know that speed of light in vacuum is

.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).
So:

λ

</span>⇒ λ

⇒ λ

⇒ <span>λ</span>
It would eventually go extinct. If you put a shark in a fresh water pond and it can't adapt to fresh water it will die.
Answer:
True
(I am not 100% sure because the question is very short with no context, but I believe it to be true)
