CBSE Class 9 - Characteristics of Sound Waves Videos
Frequency and time period
This video describes the calculation of frequency and time period when the number of waves and time required for the waves to pass is known
- What is the SI Unit of "Intensity of Sound"?
- Formula for frequency
- Name the characteristics of sound that help us to distinguish and note played on a sitar and a violin
- Difference between intensity and loudness
- Does plants affected by sound or not
- Soundwaves of wavelength X travel from a medium in which velocity is Vm/s into another medium in which if velocity is 3m/s, what is the wavelength of sound in the second medium?
- How SONAR and ultrasonic sounds are different from each other?
- Would the speed of sound on a warm day be different from the speed of sound on a cold day? If yes what would be the difference?
- An airplane produces a sound wave with frequency of 5 KHz and wavelength 30 m. In how much time would the sound wave cover the distance of 4 Km?
- Wavelength of a siren in air is 1.2m. And if same siren is blown under water it has wavelength 6 m in water. Find the velocity of sound in water, if the speed of sound in air is 330 m/s.
