Here is your answer which you are searching for

Answer as follows :-

$\leq  Step :- 1 \geq$

• Collect data from the given questio
• We know that the range of wavelength of visible radiation is from 4 nm to 700 nm

$\leq Step :-2\geq$

• Now , analysis the data we have given 850 nm

$\leq Step :-3\geq$

• The radiation having wavelength greater than 700 nm is termed as infra - red radiations ,
• Generally , this type of radiation only produce warmth

$\leq  Step :- 3\geq$

• Now , comes to  interpretation of the given data on the basis of analysis
• Given data 850 nm more than 700 nm
• It implies that given data only produces Warmth
• Thus , the wavelength of radiation 850 nm cannot be visible
