Use the given graph. determine the period of the function.

Step-by-step explanation:

we know that

The period of a periodic function is the interval of x-values on which the cycle of the graph that's repeated in both directions lies.

so

see the attached figure to better understand the problem

To calculate the period subtract from

ok

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
