Three fundamental characteristics of sound: speed, frequency, and intensity (loudness).

Speed: The speed of sound in air actually depends on the temperature of the air. As a standard, we will say that the speed of sound is 340m/s at 15 °C. If you are not told anything different in a question, use this value.

Frequency: If you are doing calculations of the wavelength or frequency of sound, you still use the standard formula

f = v/λ

where f is frequency, v is "phase velocity", i.e the speed of sound, and λ is the wavelength.

Loudness: The loudness of a sound depends on the wave's amplitude. The system used to measure the loudness of sounds is the decibel system, given the unit dB.

Sound is a mechanical wave produced by vibrating bodies. For example, when an object such as a tuning fork or the human vocal cords is set into vibrational motion, the surrounding air molecules are disturbed and are forced to follow the motion of the vibrating body. The vibrating molecules in turn transfer their motion to adjacent molecules causing the vibrational disturbance to propagate away from the source. When the air vibrations reach the ear, they cause the eardrum to vibrate; this produces nerve impulses that are interpreted by the brain. . All matter transmits sound to some extent, but a material medium is needed between the source and the receiver to propagate sound. This is demonstrated by the well-known experiment of the bell in the jar. When the bell is set in motion, its sound is clearly audible. As the air is evacuated from the jar, the sound of the bell diminishes and finally the bell becomes inaudible. . The propagating disturbance in the sound-conducting medium is in the form of alternate compressions and rarefactions of the medium, which are initially caused by the vibrating sound source. These compressions and rarefactions are simply deviations in the density of the medium from the average value. In a gas, the variations in density are equivalent to pressure changes. . Two important characteristics of sound are intensity, which is determined by the magnitude of compression and rarefaction in the propagating medium, and frequency, which is determined by how often the compressions and rarefactions take place. Frequency is measured in cycles per second, which is designated by the unit hertz after the scientist Heinrich Hertz. The symbol for this unit is Hz. (1 Hz = 1 cycle per second.)

While being interviewed by Robyn Ross of TV Guide on July 23, Ross asked Joe Jonas, "Any chance we can get a Camp Rock 3 on the big screen?". Joe Jonas replied, "Hey, let's do it! Camp Rock 2 has an ending where it can continue." Kevin Jonas was also quoted as telling the website J-14, "I'm up for it! 'We love going back to Toronto!'.

Although 'Camp Rock 2' is titled 'The Last Jam,'Disney Channel says it does rule out a 'Camp Rock 3.' At the August 7, 2010 D23 screening of Camp Rock 2: The final Jam, Senior Vice President of Original Movies for Disney Channel Michael Healy stated "Never say never" when asked if there would be a Camp Rock 3.

So maybe, there will be high hopes for CAMP ROCK 3

Don't TRY TOO HARD to look sexy because it will show and cheapen you, giving the guy the wrong idea. Less is best! Generally young guys enjoy seeing a young woman in a short top and short skirt (whatever's in.) Do up your hair nice, put A LITTLE make-up on (most men detest thick, cheap make-up on a girl.) Wear feminine shoes (mules, or sandles with a heel) and nothing clunky. Of course good hygiene is one of the most important things.

The most important thing of it all is to be yourself and not try to act too cool. Be pleasant, listen to what he's saying and don't be afraid to express your likes and dislikes. You can talk about your favorite group of singers, a single singer, actor or your favorite movie. If you like a certain male sport then that's almost a 98% shoe-in with a guy. DON'T talk about yourself all the time and DON'T repeat gossip. Most guys simply aren't into gossip. DON'T be afraid to act a little independent with a mind of your own. Men don't like clingy females, but some enjoy holding hands or an arm around the waist. DON'T let him come on to you on the first few dates and let him know in no uncertain terms he's going to have to get to know you to be that intimate in the future. If he doesn't date you again after this then consider yourself lucky.

If you are going to the movies, first think of two things.

1) it is going to be dark

2) most movies theaters are generally cold

Most guys really do not care what you wear, as long as you do not smell

nasty. Hygiene is really important for all dates mostly movie dates because you will be sitting next to each other for almost 2 hours. So shower, wear deodorant, and a light perfume.
