Write an equation in the form y=kx to represent this situation.

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:

angle efh= angle egh

there should be an link icon on the bottom of the text box you get. it looks like a paperclip!
