The wavelength of a sound wave in this room id 1.13 m and the frequency is 301 Hz.
1.what is the speed of the wave in the room?2.if you double the frequency of the sound wave,delermine its speed.3.what happens to the wavelength if you cut the frequency in half?how do you know?

你是要翻译么?还是想要答案?我先给你答案吧,如果要翻译的话再追问.1:The speed in the room is around 340m/s2:Even the the frequency of the sound wave is doubled, the speed will be the same.3:The wavelength will be doubled if the frequency is cut to half, because the speed does not change, so the length will change. c = f λ.
