Answer
a. $\lambda=3.00\times10^{5}m$
b. $\lambda=0.343m$
c. No
Work Step by Step
a. Use equation 22–4, $c=\lambda f$.
$$\lambda=\frac{c}{f}=\frac{3.00\times10^8m/s }{1.00\times10^{3}Hz}$$
$$\lambda=3.00\times10^{5}m$$
b. Repeat, now using the speed of sound.
$$\lambda=\frac{c}{f}=\frac{343m/s }{1.00\times10^{3}Hz}$$
$$\lambda=0.343m$$
c. No, you cannot hear an electromagnetic wave; it does not move the air.
