Practice Other Topics from Sound
In this topic, we will learn in detail about the propagation of sound. It explains briefly where a sound is propagated by the to and fro motion of particles of the medium.
In this topic, we will learn about the material medium, which is required for sound propagation. We will study the different types of the media through which it can propagate, and the phenomena of propagation in materials.
This topic explains the concept of waves in detail. Waves are made up of compressions and rarefactions. We will also learn the mechanism of sound propagation and role played by compression and refraction for propagation.
This topic explains sound wave and its properties. We can relate the properties of sound to the properties of a wave. The basic properties of sound are discussed in here with the help of a diagram.
The topic explains in detail about wavelength, the symbol that represents wavelength and its SI unit. Wavelength is the minimum distance in which sound waves repeats itself.
This topic explains in detail about frequency, the symbol that represents frequency and its SI unit. The number of vibrations counted per second is called frequency.
This topic describes the speed of the sound, i.e., the distance travelled per unit time by the sound wave or the disturbance caused by the wave. We will also learn the speed of sound in different mediums at 25 degree Celsius.
In this topic, we will learn the factors and the minimum distance required to hear an echo from a reflecting wall. The sound heard after reflection from a rigid surface is called an echo.
This topic discusses the phenomena of the persistence of sound after it has been stopped as a result of repeated reflections known as reverberations. Through practice questions and answers, this concept is made more clear over here.
In this topic, we will learn about the range of hearing in humans and the sound ranges that are beyond the normal hearing of humans and are also discussed here.
