What will be the increase in frequency

Reference no: EM13248001

Baseball scouts often use a radar gun to measure the speed of a pitch. One particular model of radar gun emits a microwave signal at a frequency of 10.525 GHz.

What will be the increase in frequency if these waves are reflected from a 60.0mi/h fastball headed straight toward the gun? (Note: 1 mi/h = 0.447 m/s )

The correct answer is 1880 Hz. I feel like I am doing something wrong because I keep getting 2008 Hz. Can you please show work when answering the question?
