7. Sound

Sound is a type of energy caused by vibrations and travels as a longitudinal wave through various media. It has distinct characteristics, including wavelength, frequency, amplitude, time period, and speed, and can be classified into audible, infrasonic, and ultrasonic ranges. The reflection of sound follows similar principles to that of light, with practical applications in areas such as medical imaging and underwater navigation.
