How does the de-Broglie wave length vary with momentum of moving particle..9.Name the Spectral Series of Hydrogen atom which lines in the uv region of electromagnetic spectrum.10.What are Isobars?​

Answer»

Answer

Gauss's law in Magnetism.

the surface integration of magnetic field for closed loop is always ZERO

it proves that MONOPOLE don't exist in nature

UV radiation is widely USED in industrial PROCESSES and in medical and dental practices for a variety of PURPOSES, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning.

optical fiber works on total internal reflection

i hope this helps you mark it as brainiest
