Write 'true' or 'false' for the following statements: 1. Ultrasonic waves are used for homogenizing milk. 2. The sensation of any sound persists for 1/20th of a second in our ear. 3. Loudness distinguishes a feeble sound from a loud sound of the same frequency. 4. The pitch of the sound produced is determined by the wave nature of the vibrating body. 5. The quality of sound is produced due to a change in waveform.

Step 1
Ultrasonic wave is used for homogenising milk. This statement is true because ultrasonic waves are used to break down fat globules in milk, resulting in a more uniform and smooth texture. So, the answer is $\textbf{true}$. Show more…

TRUE OR FALSE 1. Compressions are regions of low air pressure 2. Sound waves are considered electromagnetic waves 3. Rarefaction region is where the particles are close to one another 4. Sound waves cannot travel in a void space. 5. The wavelength of sound waves can be measured at the distance from one rarefaction to another adjacent comparison 6. Longitudinal waves can have either compression or rarefaction 7. Light waves are transverse waves 8. Light travels faster than sound 9. The speed of light in a certain medium is slower than its speed in a vacuum 10. The higher the frequency of light the longer its wave length

Write true or false. Correct the false statements. 1. The four whorls of a typical flower arise from the tip of the pedicel. 2. Anther, style and stigma are the parts of a carpel. 3. A stamen has a long stalk called style. 4. The transfer of the pollen grains from the anthers to the stigma of a flower is called fertilization. 5. Most insect-pollinated flowers produce nectar.

Rarefaction is a term used to describe the region of sound wave where the particles in the medium of propagation are concentrated. True or False. As you move away from the source of sound, the intensity of sound, assuming a spherical surface, decreases by the square of the distance. True or False. In order to maintain an accurate time, the length of a grandfather clock (a.k.a simple pendulum clock) must be increased when the acceleration due to gravity is increased. True or False. The propagation of a sound wave causes the medium of propagation to also move. True or False.
