State the wavelength range of electromagnetic radiation to which our eyes are sensitive. |
|
Answer» Our eyes are sensitive to light (electromagnetic radiation). Its wavelength range is 400 nm to 700 nm. [Note: Wavelength (λ) goes on decreasing and frequency (ν) goes on increasing from red (λ ≃ 700 nm) → orange → yellow → green → blue → indigo → violet (A ≃ 400 nm). c = vλ, where c is the speed of light in vacuum.] |
