FAQs on Mindmap: Sound - Science Class 8
| 1. How does sound travel through different mediums? |  |
Ans. Sound travels through different mediums, such as air, water, and solids, by creating vibrations. In air, the sound waves cause air particles to vibrate back and forth, transferring the sound energy. Similarly, in water, sound waves make water molecules vibrate. In solids, like walls or floors, sound waves are transmitted through the vibration of the particles in the material.
| 2. What is the relationship between frequency and pitch of a sound? | |
Ans. Frequency and pitch are closely related in the context of sound. Frequency refers to the number of vibrations or cycles per second, measured in Hertz (Hz). Pitch, on the other hand, refers to how high or low a sound is perceived. Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. Therefore, a sound wave with a higher frequency will be perceived as a higher pitch.
| 3. How does sound intensity affect its volume? | |
Ans. Sound intensity refers to the amount of energy the sound wave carries per unit area. It determines the volume or loudness of the sound. The greater the sound intensity, the louder the sound will be perceived. Sound intensity is measured in decibels (dB), and a logarithmic scale is used to represent the range of human hearing, with 0 dB being the threshold of hearing and 120 dB as the threshold of pain.
| 4. What factors affect the speed of sound? | |
Ans. The speed of sound is influenced by several factors, including the medium through which it travels, temperature, and humidity. In general, sound travels faster in solids compared to liquids, and faster in liquids compared to gases. Additionally, sound travels faster in warmer air compared to colder air. Humidity also impacts the speed of sound, with higher humidity slowing down sound waves.
| 5. How does the Doppler effect influence the perception of sound? | |
Ans. The Doppler effect is the change in frequency or pitch of a sound wave as the source of the sound and the observer move relative to each other. When a source of sound moves towards an observer, the frequency of the sound waves increases, resulting in a higher perceived pitch. Conversely, when the source moves away, the frequency decreases, resulting in a lower perceived pitch. This effect is commonly observed with moving vehicles or sirens.
