| Wave | A | B | C | D | E |
| Frequency | 5000Hz | 1000Hz | 600Hz | 10Hz | 30000Hz |
i. Identify the wave which is not heard by our ears.
ii. Which one is the sharpest sound? and why?
iii. Which wave has the longest wavelength?
iv. How many compression and rarefractions are formed per second in wave D?
i. Here, wave D and wave E are not heard by our ears because audible frequencies for humans is 20Hz to 20,000 Hz. ii. Here, wave E is the sharpest sound. The intensity of sound is directly proportional to the square of frequency of the .....
Since there are 5 geometric means between the two numbers 1/2 and 32, we have to find 7 (=5+2) terms in G.P. of which 1/2 is the first, and 31 the seventh. Let r be the common ratio;
then t7 = 32 or, 32 = (1/2) . r7-1 = .....
