Question

Given the following information:

#1.) If wave (a) has a wavelength of 5.0 m and a frequency of 1.5×108 cycles/s, what are the wavelength of wave (b)? Express your answer in (meters) using two significant figure.

#2.) What is the frequency of wave (b)? Express your answer in (cycles/s) using two significant figure.

Wavelength Electromagnetic waves. Like water waves, electromagnetic radiation can be characterized by a wavelength. Notice that the shorter the wavelength, 1, the higher the frequency,v. The wavelength in (b) is half as long as that in (a), and the frequency of the wave in (b) is therefore twice as great as the frequency in (a)

Explanation / Answer

#2) Given that:

Wavelength in (b) is half of wavelength in (a)

So, the wavelength in (b) = 5.0 ÷ 2 = 2.50 meter

#2) Frequency of (b) = 2 × frequency of (a)

= 2 × 1.5 × 108 cycle/s

= 3.00 × 108 cycle/s
