The freezing point ..... :)
I will be brief
5. There is no displacement as it didn't move
6. Time cannot go backwards so it cannot be negative
Answer:
The wavelength is 
Explanation:
From the question we are told that
The frequency of operation of the microwave is 
Generally the wavelength is mathematically represented as

Here c is the speed of light with value 
So

=>
converting to nanometer

The best place to put PFDs while you are out on your boat is at the top deck of your boat. PFDs must be placed at an area where it is easily accessible, especially in times of accidents, without any unnecessary gear or objects covering the PFDs, but it is best to wear a life jacket during the whole duration of the boat trip.
V = f(lambda)
5/1 = lambda
lambda = 5
