Question

A wave has a frequency of 3,5MHz and a wavelength of 85,5 m. What is the wave velocity through

air (air, n=1,00)?

Answer 1

velocity = 29925×10⁶ m/s

Step-by-step explanation:

Given data:

Frequency = 35 MHz

Wavelength = 855 m

Velocity = ?

Solution:

MHz to Hz

35×10⁶ Hz

Formula:

velocity = Wavelength × Frequency

velocity = 855 m × 35×10⁶ Hz

velocity = 29925×10⁶ m/s

Hz = s⁻¹
