5. Points P and Q on the far bank of a river are sighted from points A and B.
The lines of sight form the angles shown in the given diagram.

If the banks are parallel and AB = 25 mi, find PQ.

answer: options

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:

the correct answer is 1.7
