If a radio station is tuned at 1600 kHz what the image frequency?

The image frequency is the frequency that, when mixed with the desired signal, produces the intermediate frequency (IF) in a superheterodyne receiver. It is calculated by subtracting the IF from the desired frequency.

In this case, the IF is typically 455 kHz, so the image frequency is:

$$f_{image} = f_{desired} - 2 \times IF$$

$$f_{image} = 1600 kHz - 2 \times 455 kHz$$

$$f_{image} = 690 kHz$$

Therefore, the image frequency for a radio station tuned at 1600 kHz is 690 kHz.
