Short Answers<\/strong><\/span><\/h3>\n

Question 1:<\/strong> What is a sound<\/a>? What causes it to produce?
\nAnswer:<\/strong> Sound is a form of energy. It is that external physical cause which affects the ear to produce the sensation. Sound is produced only when some material body is made to vibrate.<\/p>\n

\"\"\"\"<\/p>\n

Question 2:<\/strong> Define the term Amplitude.
\nAnswer:<\/strong> The maximum displacement from mean position in vibration of a wave is called amplitude.<\/p>\n

Question 3:<\/strong> Define the term Frequency (as applied to sound waves)
\nAnswer:<\/strong> The number of vibrations per second taken by a wave is called its frequency.<\/p>\n

Question 4:<\/strong> What are mechanical waves?
\nAnswer:<\/strong> Mechanical waves are waves which needs material medium for its propagation i.e., cannot travel in vacuum, e.g. sound waves<\/p>\n

Question 5:<\/strong> Name the unit used for measuring the sound level.
\nAnswer:<\/strong> Unit for measuring sound level\u2014Decibel.<\/p>\n

Question 6:<\/strong> Name the subjective property of sound related to its frequency.
\nAnswer:<\/strong> The subjective property of sound related to its frequency is pitch.<\/p>\n

Question 7:<\/strong> Name the subjective property of light related to its wavelength.
\nAnswer:<\/strong> The subjective property of light related to its wavelength is colour.<\/p>\n

Question 8:<\/strong> State two differences between light waves and sound waves.
\nAnswer:<\/strong> Two differences between light waves and sound waves.<\/p>\n\n\n\n\n\n
Light waves<\/strong><\/td>\nSound waves<\/strong><\/td>\n<\/tr>\n
1. Light waves do not require a medium for propagation.<\/td>\nSound waves require a medium for propagation.<\/td>\n<\/tr>\n
2. Light waves travel with a speed of 3 \u00d7 108<\/sup> m\/s.<\/td>\nSound waves travel with a speed of 332 m\/s.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Question 9:<\/strong> How does frequency affect a musical sound?
\nAnswer:<\/strong> In musical sound the component wave do not change their wavelength hence the frequency and amplitude affect a musical sound like this.<\/p>\n
