Colour? Change Experiment?| @MR. INDIAN HACKER shorts #theexking #shorts #experimentshorts #viral

Explain in short perception of colour.

In the Coolidage tube experiment, if the applied voltage is increased to three times, the short wavelength limit of continuous X- ray spectrum shift by 20 pm. What is the intial voltage (in kV) applied to the tube?

While performing an experiment, a student observes that when he heats some green crystals in a boiling tube, the colour of the crystals changes to brown and a gas evolves which smells like burning sulphur . Interpret the observations and results.

A viral preparation was inactivated in a chemical bath. The inactivated in a chemical bath. The inactivation process was found to the first order in virus concentration and at the beginning of the experiment 2.0% of the virus was found to be inactivated per minute The k for the inactivated per minute The k for the inactivated process is (assume that there is no change in rate in the interval)
