Which statement best describes who the period and frequency of electromagnetic was change between gamma rays and microwaves? a) the period and frequency stay the same. b) the period increases and the frequency decreases. c) the period decreases and the frequency increases. d) the period increases and the frequency increases.

Answer : The period increases and the frequency decreases.

Explanation :    

Gamma rays are the rays having frequency( ) greater than and frequency of microwave lie between 300 MHz to 300 GHz.

Since,

So, as we move from gamma rays to microwaves the energy increases because frequency is increasing.

Also, Time period

We can say that as the time period increases, frequency decreases.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
