Hi,
I have a question about mechanical waves (sound and ultrasonic waves
for instance).
I am familiar with wavelength formula: lambda=C/F
But I am not able to understand why a sound wave (10 KHz for instance)
which has a LONGER wavelength than an ultrasonic wave can pass through
a barrier like a thin wall while an ultrasonic wave (50 KHz for
instance) will reflect from it??
I know that my question is a physical question not an electronically
question but I noticed that problem when I was working with different
speakers.
Thanks for any advice.
