explain what ( if anything) is wrong with the following student\'s statement: \" our solution is red, so we should set the spectrophotometer to the red light range ( 700nm) to measure its absorbance.\"

Solution

a solution absorbs a color wavelength and reflects(shows) other color wavelength.

Red color solution absorbs wavelength corresponding to Violet color.

Hence wavelength should be fixed in range 400 nm to measure absorbance
