It’s hard to believe that the end of the budget year is fast approaching. If your department has unspent funds now is a great time to consider acquiring one or more of PASCO’s premier instructional apparatus. The very popular featured products below are all in stock and can be shipped in time to make this year’s budget deadline.
1. Microwave Optics
The transmitter emits a large 3 cm wavelength that makes it easy for students to visualize and understand electromagnetic interactions. The system can be quickly adjusted with magnetic mounting components, rotatable transmitters and receivers and a Goniometer with rotatable arms featuring built-in degree and millimeter scales. Durably designed, the system will provide years of trouble free labs with components made of either cast-die aluminum or stainless steel.
WA-9314C ($2995) – Basic System for investigation electromagnetic interactions
WA-9316A ($3995) – Advanced System includes accessories for Brewster Angle and Bragg Diffraction experiments
2. Educational Spectrophotometer System
This very versatile system’s open design is ideal for education. When used with Capstone software, students can graph the spectral lines of gases; precisely measure the relationship between angle wave length and intensity; and analyze the transmission characteristics of filters and chemical solutions. The sensors can connect to PASCO’s full range of interfaces including the very affordable Wireless Airlink or the powerful 850 universal interface.
OS-8450 ($1912) – Includes Light and Rotary Motion Sensors and Optics Bench
OS-8537 ($1257) – Sensors and Optics Bench not included
3. Photoelectric Effect System
Planck’s constant is a central quantity in quantum mechanics and its discovery was one of the greatest breakthroughs in understanding the nature of light. With this system your students will be able to perform the photoelectric experiment to determine Planck’s Constant to within 5%. Students will also be able to verify that stopping voltage is independent of intensity and find the characteristics of the photodiode. Can be used with the 850 Interface and Capstone software
SE-6614 ($3156) – Basic System, includes Mercury Light Source with Hg tube
SE-6609 ($5666) – Basic System plus DC Current Amplifier and DC Power Supply
4. Electron Charge-to-Mass Ratio System
This system reproduces J.J Thompson’s landmark experiment to calculate the charge-to-mass ratio of the electron. A very sharp and visible electron beam within the vacuum tube allows for its radius (R) to be easily measured using the built-in fluorescent scale. The system also provides a measurement for the accelerating potential (V) applied to the electron gun as well as the magnetic field (B) produced from applying a current to the Helmholtz coils. With these measurements students can then accurately calculate the electron’s charge to mass ratio using the formula e/m=2V/B2R2.
SE-9629 ($6555) – Complete system with e/m tube and power supplies
