Practice Other Topics from Sound

Science>Physics>Sound>Production of Sound

With the help of various activities, we will come across the production of sound. It explains how the vibrating tuning fork produces sound. We will also observe the result when both the prongs of the vibrating tuning fork are dipped in water.

Science>Physics>Sound>Propagation of Sound

Sound is produced by vibrating objects. Here, we will study about the types of materials or substances required for the transmission of sound. It discusses characteristics of sound waves and also mentions the speed of sound in different mediums.

Science>Physics>Sound>Types of Waves

This topic categorises waves based on its propagation and direction. We will study the longitudinal and transversal waves in detail. Graphical representation of these waves is also shown here.

Science>Physics>Sound>Characteristics of the Sound Wave

In this topic, we will learn about the characteristics of sound waves, including wavelength, time period, frequency, amplitude, and speed. It also discusses the relation among them with their respective units.

Science>Physics>Sound>Characteristics of a Musical Sound

This topic describes the production of sound through various musical instruments. It explains the sound of percussion, wind and string instruments along with their characteristics. We will also understand the wave pattern of musical sound and noise.

Science>Physics>Sound>Reflection of Sound

This topic is all about the reflection of sound. It discusses the concept of echo and reverberation in detail. We will come across various solved examples as well. Furthermore, it highlights different uses of multiple reflection of sound.

Science>Physics>Sound>Range of Hearing

In this topic, we will know the audible range of human beings and animals. It describes that a hearing aid is an electronic, battery-operated device. It explains how the hearing aid receives sound through a microphone and also highlights its use.

Science>Physics>Sound>Applications of Ultrasound

Ultrasounds are high frequency waves. This topic highlights the applications of ultrasound. It includes a description of ultrasound scanner and SONAR. We will also learn how ultrasound is sent by the transmitter and received by the detector.

This topic explains the construction of a SONAR. SONAR is a device that uses ultrasonic waves to measure the distance, direction, and speed of underwater objects. It also details the mechanism of SONAR along with its applications.
