Product Description
We offer a complete experiment for the study of Planck's Constant
and verification of inverse square law of radiation using a
photocell.
1. Determination of Planck's Constant and Work Function of
Materials by Photoelectric Effect
It was observed as early as ***5 that most metals under influence
of radiation, emit electrons. This phenomenon was termed as
photoelectric emission.
The experimental facts provided the strong evidence that the
electromagnetic field is quantified and the field consists of
quanta of energy E= hn where n is the frequency of the radiation
and h is the Planck's constant. These quanta are called
photons.
2. To verify inverse square law of radiation using a
photoelectric cell
THE APPARATUS CONSIST OF THE FOLLOWING:-
(1)
Photo Sensitive Device: Vacuum photo tube.
(2)
Light source: Halogen tungsten lamp *2V/*5W
(3)
Colour Filters: **5nm, **0nm, **0nm, **0nm &
**0nm
(4)
Accelerating Voltage: Regulated Voltage Power Supply
- Output: ± *5V continuously variable through multi-turn
pot
- Display: 3 ½ digit *-segment LED
- Accuracy: ± 0.2%
(5)
Current Detecting Unit: Digital Nanoammeter
It is high stability low current measuring instrument
- Range: ***0 μA, **0 μA, *0 μA & 1 μA with **0% over
ranging facility
- Resolution: 1 nA at 1 μA range
- Display: 3½ digit *-segment LED
- Accuracy: ± 0.2%
(6)
Power Requirement: **0V ±*0%, *0Hz or
**0V ±*0%, *0Hz. as required
(7)
Optical Bench: The light source can be moved along it to
adjust distance between the light source and the phototube, scale
length is **0mm. A tube is provided to install colour filter and a
focus lens is fixed in the back end.
The circuit is all electronic using transformer and electronic
components Viz. IC’s, transistors, capacitors and resistance etc.
The whole circuit operates on **0V ± *0% *0 Hz AC and mounted in a
metallic cabinet which is grounded through the grounding lead of
power connector and hence safe towards electrical hazard, if
any.
The set-up is complete in all respect, no additional
accessory is required.
