An easy, economical way to see and measure light and color from different light sources!
Brighter and clearer than other spectroscopes, use this durably constructed, economical tool to see and measure different spectra. Separate light into its component colors. Contrast the differences between fluorescent and incandescent lights. Measure which wavelengths are absorbed by different materials. Our new Light Source Adaptor and Light Sources make it easier than ever to see bright-line emissions spectra and unveil the atomic origin of light. Supplied with an excellent set of instructions that reviews light theory and diffraction gratings, it provides suggestions for numerous experiments in light and color.
A built in scale measures light wavelengths from 400nm to 700nm with a precision of +/- 5 nm. Standards
In using this product, national and states’ science education standards are covered. Some examples are provided here. These are representative, however. Check with your state to find the exact standards.
Each kind of atom or molecule can gain or lose energy only in particular discrete amounts and thus can absorb and emit light only at wavelengths corresponding to these amounts. These wavelengths can be used to identify the substance.
Relate colors to wavelengths of light.
Explain how we see colors of objects.
