Q

A RADAR operating at a frequency of 3 GHz has a wavelength of approximately:

🔍 Key Concepts

• Relationship between frequency, wavelength, and speed of light for electromagnetic waves • Approximate value of the speed of light in meters per second • Converting between meters and centimeters

💭 Think About

• What is the formula that links wavelength, frequency, and the speed of light for radar waves? Write it down and solve it step by step. • If the speed of light is about 3 × 10^8 m/s and the radar frequency is 3 × 10^9 Hz, what wavelength (in meters) do you get? • Once you find the wavelength in meters, how do you convert that value to centimeters, and which choice is closest?

✅ Before You Answer

• Use the formula λ = c / f, where λ is wavelength, c is speed of light, and f is frequency. • Be sure to use consistent units: meters per second for speed, hertz (1/second) for frequency. • After calculating in meters, convert to centimeters by multiplying by 100, then compare carefully with the answer choices.
