A hot metal emits photon of light with energy 3.0 (10*-19) J. Calculate the frequency and wavelength of the photon ?

Text Solution

Verified by Experts

Activation of adsorbent means to increase adsorbing power of an adsorbent. This can be achieved by increasing the surface area of the adsorbent. The surface area can be increased by following methods : i) By breaking adsorbent into smaller pieces. i) By making surface of the adsorbent rough.
