 Light Measurement Kit (110/60 volt only) - 10 labsYour students can now determine the luminosity of the sun using a 200-watt light bulb. They can explore the relationship between the apparent brightness of a luminous object and the distance to the object. Using a null photometer constructed from paraffin and aluminum foil, a student can compare two light sources to determine the luminosity of or the distance to one of the sources. The photometer can then be used to compare a 200-watt light bulb with the sun to estimate the sun's luminosity. The kit also contains a 1-foot length of .01-inch optical fiber that, when taped to a flashlight, becomes an "artificial star." With an output of one-millionth of a watt, this small source of light is compared to a star in the sky and the distance to the star can be estimated. Recommended for astronomy, physics, and physical science at the high school through college level.Our Price: $65.00 |
