About This Product
Ultrasound acts as a direct analogue of the properties of electromagnetic waves, so reflection, interference and diffraction of sound can be shown with this kit. The horns constrain the ultrasonic energy into the narrow beam that certain experiments need. The longitudinal, unpolarised nature of the vibrations means polarisation experiments cannot be performed as optical analogues. Individual units in the range are listed separately.
Frequently Asked Questions
Q1. Can polarisation be demonstrated with the Ultrasonics Kit?
No. The longitudinal, unpolarised nature of the ultrasonic vibrations does not allow polarisation experiments to be performed as optical analogues.
Q2. What wavelength does the kit produce?
At its operating frequency of 40 kHz, the wavelength in air is approximately 8.3 mm under normal atmospheric conditions.
