Question

When the white light is thrown on a body that absorbs all the wavelengths of the visible spectrum, how will it appear to human eyes ?

• A. $\text{White}$
• B. $\text{Black}$
• C. $\text{Grey}$
• D. $\text{Transperent}$

Answer 1

The correct option is B $\text{Black}$

If a body absorbs all the wavelengths of the visible spectrum, then there is no visible wavelength reflected by the body and since no visible light is coming from the body, it will appear black.
