Question

In addition to cable and satellite broadcasts, television stations still use VHF and UHF bands for digitally broadcasting their signals. Twelve VHF television channels (channels 2 through 13) lie in the range of frequencies between 54.0 MHz and 216 MHz. Each channel is assigned a width of 6.00 MHz, with the two ranges 72.0 - 76.0 MHz and 88.0 - 174 MHz reserved for non-TV purposes. (Channel 2, for example, lies between 54.0 and 60.0 MHz.) Calculate the broadcast wavelength range for channel 3. (Enter your answers from smallest to largest.) Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error, m Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error, m Calculate the broadcast wavelength range for channel 4. (Enter your answers from smallest to largest.) Calculate the broadcast wavelength range for channel 5. (Enter your answers from smallest to largest.) Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error, m Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error, m

Explanation / Answer

a) For channel 2, f range = 54 - 60 Mhz
For channel 3, f range = 60 - 66 Mhz
Wavelength = c/f
Wavelength range = 4.5454m - 5m
c) For channel 4, f range = 66 - 72 Mhz
For channel 5, f range = 76 - 82 Mhz
Wavelength range = 3.658 m - 3.947 m
