ICSE Class 10 Answered

In order to hear echo why the reflector size must be greater than the wavelength of the wave??

answered-by-expert Expert Answer
This is because for reflection to take place, at first place, the reflector size must be greater than the wavelength of the incident wave. If the incident wave wavelength is comparable to the reflector size, the sound will bend around the corners of the reflector, and no appreciable reflection will take place. This is a phenomenon about which you will study in higher classes.
