Questions about Wave Period and Radio Wave Wavelength

[sinandcity]

Hi all

I was absent from school when these were done, so I missed out on some of the work (which is highly regreted).

I'm just needing to know a few things, hopefully you guys can help me out here.

The period of a wave, that's the amount of times a wave passes through a certain point, right? please correct me

and this question, How many 3m cows would fit into a wavelength of a radio wave of velocity 3x108 and frequency 106Hz.

No. The period is the time it takes one wavelength to pass a given point. Read this: http://www.physicsclassroom.com/Class/waves/U10L2b.html
