If the intensity of the light producing a photocurrent is doubled, how is that current affected?

In Young’s double slit experiment, the intensity of light coming from the first slit is double the intensity from the second slit. The ratio of the maximum intensity to the minimum intensity on the interference fringe pattern observed is

The intensity of the light coming from one of the slits in a Young's double slit experiment is double the intensity from the other slit. Find the ratio of the maximum intensity to the minimum intensity in the interference fringe pattern observed.

In a circuit when current of 4A is flown in a resistance for 1sec heat produced is 192J. If the current is doubled then heat produced in 5s in same resistance is....

In the experimental setup for a photocell, the wavelength of the light incident on the cathod is initially 0.6 times the threshold wavelength for the material of the cathode. Certain change in the experimental setup are given in column A and their possibel effects are given in column B. {:("Column A","Column B"),((i)"The intensity of the incident light is doubled but the frequency remains unaltered",(a)"Photocurrent remains the same"),((ii)"Both the intensity and wavelength of the incident light are doubled",(b)"Photcurrent falls to zero"),((iii)"The intensity of the incident light is doubled and its wavelength is made half",(c)"Stopping potential increase"),((iv)"The intensity of the incident light ramains the same and the wavelength is made half",(d) "Photocurrent increases"):}

In a photoelectric experiment, if both the intensity and frequency of the incident light are doubled, then the saturation photoelectric current

if the intensity of light is made 4I_0 , then the saturation current will become

If the intensity of sound is doubled, by how many decibels does the sound level increase ?
