    High School What frequency and wavelength do radar and sonar use?

    Can anyone tell me what frequency and Wavelength Radar and Sonar work in. I think Radar have a frequency of 300giga hertz (UHF), wavelength 0.1 Sonar is somewhere between wavelength 100k - 10k metres, frequency 3k - 30k hertz. Please help me thanks,

    High School Difference between holography and holograms

    Thanks guys. I just needed to know if holograms was ok in a holography subject. My assignment is on holography, but I thought it had to be exactly on it. SO I guess I can use holograms in this as well as holography is the process of making holograms.

    High School Difference between holography and holograms

    Oh NO really. But I can't find much information on holography. So I thought if I explain that holograhy is the process of making holograms, then explaining holograms was ok. Can you maybe post some websites I could use for holography. (OF course wikipedia). Thanks

    High School Difference between holography and holograms

    This is my opening paragraph is it good. Is the information I have placed right please check. "Holography is the process of making or the technique of making holograms. It is an advanced type of photography, which allows the image to be seen in 3D. Holograms work by bouncing laser light off an...

    High School Difference between holography and holograms

    Please explain the difference between holography and holograms. I have to do an assignment on holography, but should I research holograms aswell. Thanks

    Why is AM radio reception clearer than FM in valleys?

    OK. this is why, FM radio broadcasts travel at a thing called "straight line". Thus they pretty much only travel at straight lines (Sort of, but you get the picture) so if anything like a mountain or a wall comes in its way it will be interfered. But AM doesn't do this, it travles around the...

    Why is AM radio reception clearer than FM in valleys?

    I assume it is because of that am relies on amplitude and fm relies on frequency.

    High School How are seismic waves produced?

    Arrrr... moment magnitude scale. Thanks for that information. Quite impressive. Obsolete indeed. Thank you.

    High School How are seismic waves produced?

    Are you sure about "you cannot get earthquakes larger than about a 10 on the magnitude scale" cause check the table out in wikipedia. http://en.wikipedia.org/wiki/Richter_magnitude_scale It has a 12.55. :0

    Undergrad Why are gravitational waves so rare?

    oh wow, thanks for the information on holographs. I thought they were the same thing. damn. Thanks heaps.

    Undergrad Why are gravitational waves so rare?

    They are called that because they are just like ripples in water. but gravity in gravity waves confuses everyone as it does not have much to do with gravity waves :D

    Undergrad Why are gravitational waves so rare?

    Thats ok, is you above statement wrong "If gravity waves exist, they're extremely common (they're produced whenever anything changes shape), but they're also extremely weak, and extremely difficult to detect". Yes a lot of people get themselves confused with gravitational and gravity waves, and...

    High School How are seismic waves produced?

    Yes makes very sense, thank you so much.
