Solve the equation P = 3L + 2W for w

W= (P-3L) / 2

Step-by-step explanation:

P = 3L + 2W

then:

P - 3L = 2W

(P-3L)/2 = W

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:
