Question

Calculate the maximum wavelength of the radiation which can ionize the hydrogen atom in ground state. If radiation of wavelength less than the maximum wavelength is absorbed by the hydrogen atom in ground state, will it ionize the hydrogen atom and provide kinetic energy to the emitted electron?

Answer 1

Explanation:

Cocoons are collected and kept under the sun, or boiled, or exposed to steam.

This helps in separating out the silk fibres. The process by which silk thread is separated from the cocoon is called reeling the silk.
