Given the diagram below, what is cos(45") ?
A. 22
B.
C.
V2
D. 4,2

constants mean the stopped points or the points on a graph that nothing is changing, hope this

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:
