Product Description

Description:

Einstein postulated that light consists of a quantum of particles, called photon whose energy E is proportioned to the frequency n,by an equation, E = hn, where h is plancks constant.  In this experiment,narrow band interference filters are used to select wave length, each filter selects precisely one spectral line from the light of a high pressure mercury lamp. The mono chromatic light falls on the cathode of the photocell. A capacitor, connected between cathode and anode of photocell, charged by anode,is used. Electro meter amplifier is used to measure the voltage at capacitor without current.

Experiments:

  • To determine Plancks Constant by Cs Photocell.

Features:

  • Multipurpose electrometer amplifier.
  • CS photo cell.
  • Multipurpose power supply.
  • Monochromatic light source may be used in many other experiments also.
  • Hexagonal optical bench.
