Using the spectroscope, observe the spectra produced by the incandescent bulb Christmas lights and LEDs provided in you kit. Sketch your observations on the scales provided in Solids and Light Activity 2 (pages 2-5 to 2-7). You make like to use colored pencils or markers to indicate the position of color(s). Add a written description to record which colors seem bright.
In terms of the color, intensity, and patterns of light emitted, how is the incandescent lamp similar and different to the gas lamps?
Compare your observations for LEDs and incandescent lamp. How are they similar? How are they different?
Summarize the results of your observations of the LEDs by completing the table below.
Summarize the results of your observations of the light emitted by each source, their spectra and their physical characteristics by completing the table below with the differences and similarities among the three light sources.
