Question

The wavelength of visible light ranges from 650 nanometers to 850 nanometers, where 1 nm = 1 × 10^−7 cm. Express the range of wavelengths of visible light in centimeters.

Answer 1

Answer:

So wavelength range of visible light will be $=650\times 10^{-7}=6.5\times 10^{-5}cm$ to $=850\times 10^{-7}=8.5\times 10^{-5}cm$

Step-by-step explanation:

We have given wavelength range of visible light is 650 nm to 850 nm

We have given that $1nm=10^{-7}cm$

So for converting nm to cm to we have to multiply with $10^{-7}$

So 650 nm $=650\times 10^{-7}=6.5\times 10^{-5}cm$

And 850 nm $=850\times 10^{-7}=8.5\times 10^{-5}cm$

So wavelength range of visible light will be $=650\times 10^{-7}=6.5\times 10^{-5}cm$ to $=850\times 10^{-7}=8.5\times 10^{-5}cm$
