FAQs
1. How does this apparatus differ from traditional Planck’s Constant setups?
The solar cell-based design offers higher sensitivity at lower light intensities compared to vacuum phototubes, eliminating the need for high-voltage power supplies while maintaining measurement accuracy across the visible spectrum.
2. What wavelength range does the included light source cover?
The monochromatic light source spans 400-700 nm with 20 nm bandwidth filters, providing discrete wavelength selection for comprehensive photoelectric effect studies without requiring external spectrometers.
3. Can this kit be used with standard laboratory power supplies?
Yes, the apparatus operates on standard 220-240V AC power with built-in voltage regulation, and includes all necessary adapters for compatibility with common Indian laboratory power outlets.
4. What maintenance procedures are recommended for long-term use?
Regular cleaning of optical surfaces with isopropyl alcohol and storage in the provided dust-proof case maintains performance. The solar cell requires no special maintenance beyond occasional contact cleaning with deionized water.
5. Are replacement filters available separately for this model?
While the complete set includes all necessary filters, individual replacement filters matching the original specifications can be sourced through authorized dealers using the part numbers listed in the user manual.
