Chapter 20 - Atomic Spectra - 10

Physics Class 12
1. The heat of the Laser seals off capillaries and lymph vessels to prevent spreading of the disease.

2. Laser is the potential energy source for inducing fission reaction.

3. The speed of electron is same as the speed by light.

4. The radius of typical nuclei is less than 10-14m.

5. In spontaneous emission an atom emits a photon of energy hf=E1-E2 in any arbitrary reaction.

6. In helium-neon laser both helium and neon have nearly identical metalstable states
