Planck’s Constant
Catalogue No: 1110845
Seven LED’s of different wavelengths mounted on a moulded plastic case (142x80x40) mm approx, selectable through a rotary switch. The apparatus uses a 5V DC input external 4mm sockets. To monitor the current and voltage across each LED additional 4mm sockets are provided to connect voltmeter and ammeter. The operating voltage for the LED’s can be adjusted with the help of potentiometer.

Planck’s Constant Apparatus
Catalogue No: 1110855/2
Uses SB- CS photoconductive cell, which works on UV – visible light spectrum range. Planck’s constant can be completed by finding the reverse potential applied to make photo cell current zero. A aperture provided for light of different colors (wave long the) incident on photo cell. BNC socket provided for connecting to Picometer. Picometer (Cat. no. 1091926) available separately.

Planck’s Constant Apparatus
Catalogue No: 1110851
A simple portable device for determination of planck’s constant. On providing input of 5V DC, the voltage across the three LEDs, can be varied through a knob and can be measured across a pair of 4mm sockets. The voltage at which a particular LED glows helps in computing the planck’s constant. Complete assembly mounted in plastic case, with circuit printed on it. Provision for external LEDs with fixed as well as variable voltage. Complete with user instruction manual.
