1/f = 1/d + 1/d'
How do I find d'?

d= 2f

Step-by-step explanation:

Solve the rational equation by combining expressions and isolating the variable 'd'.

Hope this helped.

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:
