Question

According to the modern theory for nature of light, the light has ________.

• A. particle nature only
• B. wave nature only
• C. both wave and particle (dual nature)
• D. Neither particle nature nor wave nature

Answer 1

The correct option is C both wave and particle (dual nature)

According to modern theory of light, light exhibits both behaviour- wave nature as well as particle nature. In other words, light show dual nature.
Relation between wave nature of light and particle nature is given by de Broglie hypothesis.
$\lambda =\frac{h}{p}$
