I need help with an algebra problem for my astronomy class re: radio waves

[MrsBrady]

I understand the formula, but I don't know what the proper unit conversions should be...

I need to solve for the SIZE of a wavelength in meters

λ in meters = speed of light at 3x10⁸ m/s /(divided by) 1.5x10⁸HZ the frequency

I know it's two something...

But I don't get if it's 2 meters or .02 meters or 2x10¹⁶ or .02x10¹⁶


It's a TV radio wave, so I know it can be rather large...so 2 meters or more is not out of the question.
I just don't if I need to convert hz to khz or m/s to km/s.

It's a television signal...so would it be 2, just because of that? VHF is around 1m in wavelength.

I couldn't get the 16 superscript to work, but that is 16

1. too heavy this time of night????

2. No conversion is necessary.

The unit of frequency, the Hertz (Hz), is one cycle per second.

Thus 1 Hz = 1 / (1 sec).

If the frequency is 1.5 x 10^8 Hz , then the wavelength is 2 meters.

3. thank you
