Question

Wavelength of radiation 850nm falls on a surface. Will this surface be visible or not? Explain

Answer 1

Answer:

Collect data from the given question

We know that the range of wavelength of visible radiation is from 4 nm to 700 nm

Now , analysis the data we have given 850 nm

The radiation having wavelength greater than 700 nm is termed as infra - red radiations ,

Generally , this type of radiation only produce warmth

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
