WebReflection of sound waves Echoes. Sound waves can reflect off surfaces. We hear reflected sound waves as echoes. Hard, smooth surfaces are particularly good at reflecting sound. WebOct 4, 2024 · Reflection of sound waves can cause an echo or a reverberation. This is determined by the length of time between the original sound and the reflected sound. If …

WebJan 25, 2024 · But, in case of a sound wave, if it gets reflected from the rigid boundary, we do not consider a phase difference of "Pi". We consider the reflected wave to be in the same phase. I understand that we can represent a sound wave in two ways: Pressure Wave. Variation of pressure with time and position. Displacement wave. WebInterestingly, the speed of sound is over 4 times faster in water than it is in air. So, any sound wave underwater can escape into the air*, and total internal reflection occurs instead for waves entering the water from the air! Furthermore, since the speed of sound is so much different for air and water, the critical angle is only 13 degrees!
