Lab# 10: Speed of Sound Experiment I. A sound created at the Sun will (5) A) take a long time to reach to the earth as sound travel very slowly in empty space B) reach to earth faster than expected as sound will be travelling very fast through empty space c) never reach the earth. d) Divide the di stance between the sun and the earth by the speed of sound at to find the time needed t earth. 2. n order o doublethe wavlkngth of ound wave,yo should e5) (a) double its amplitude (b) double its frequency (c) halve its amplitude (d) halve its frequency

Explanation / Answer

1) sound waves does not travels in a vacuum. it requires the medium

so sound from the sum will never reach the earth

option c

2) speed = wavelength*frequency

if speed remains constant

if wavelength gets double then frequency becomes halve

option d is the correct answer
