Led Array

ARCO LED Array can be used to study the relation between light color and wavelength. Planck/s constant can also be determined by knowing voltage & the wavelength across different color LEDs. Features: 1. Eleven different color LEDs with different wavelength are mounted in a vertical column. 2. Rotary switch is provide to select any individual LED or all together. 3. 4mm safety sockets are provided to check the voltage across individual LED. Specifications: 1. Input: 5V DC, 1.5 Amp Power Adaptor. Mechanical Specifications: 1. Case: ABS Injection Moulding. 2. Dimensions: L (140mm) X W (80mm) X H (268mm) approx. 3. Weight: 400gms approx.
