About This Product
With the transmitter and the wide-angle receiver, students can carry out qualitative demonstrations of microwave communications and wave effects such as reflection, absorption, refraction, standing waves and interference. The probe receiver gives more precise results over a shorter range for quantitative work, and using all three units covers all aspects of the topic.
Frequently Asked Questions
Which units are needed for a working system?
The transmitter and the wide-angle receiver are enough for qualitative demonstrations of microwave communications and wave effects. For quantitative measurements the probe receiver is added, and using all three units covers all aspects of the topic.
How are the units powered?
The transmitter and receiver run from mains plug-top units, which are supplied. The probe detector uses the same type of plug-top supply as the receiver, and an additional power supply unit can be supplied if requested.
What accessories come with the system?
The accessory set comprises 2 metal reflection/diffraction plates with base, an acrylic reflection/transmission plate with base and 1 narrow metal plate to provide Young's slits.
