How many vibrations per second

A certain radio wave has a wavelength of 7 inches. An FM radio station broadcasts at Calculate the wavelength of the corresponding radio waves. A harmonic wave is traveling along a rope. The oscillator that generates the wave completes A given crest of the wave travels cm along the rope in a time period of What is the wavelength?

Thank CHEM! Chemistry Suppose you are standing m from a radio transmitter. Which letter shows the type of wave that can be Chemistry A radio station's channel, such as Physics Radio amateurs are permitted to communicate on the "10 meter band. Here are a couple objects to allow your exploration of Pitch and Frequency in Max. By pushing the "I" key on your computer keyboard, you will create a flonum object at the precise location of your mouse.

However simple this object might seem, it actually is capable of displaying several very useful information. Let's duplicate this object using command D, or control D and open the inspector window.

In the inspector window we can change several attributes for the look and behavior of our object. Here we are going to take a look at the first attribute under the "Appearance" tab, the "Display Format". Do keep in mind that, under the hood, these objects are still sending and receiving numbers, the MIDI note names are just for display purposes only. Also useful for display is the kslider object, which, as with virtually all other objects in Max, also has several customizable attributes on the inspector window.

Finally, there are two other objects that you must keep under your toolbelt while working with Pitch and Frequency in Max. The mtof object will convert a midinote number to the corresponding frequency for you. And the ftom object will help you achieve just the opposite - to convert a frequency to the approximate MIDI note number. Frequency and Pitch What is frequency? Three things vibrate when sound is created: the source object the molecules in the air or another medium e.

Objectives Describe how sound is produced. Materials anything that makes a sound e. What To Do Part 1: Introducing the concept of vibration Ask the students to wave their hands in front of their faces. What is this motion called waving, shaking, jiggling, wiggling, etc.

The scientific name for this motion is vibration. All sounds begin with vibration. Can you hear the vibrations of your hands? Place all of the volunteers in a line, facing the class, with 3—4 feet of space separating them. Ask the students to act out the following sequence of events: The first student rings the bell or other sound-making device.

The second student air molecule begins to vibrate wiggle , moves toward the third student air molecule and touches them. The third student, feeling the touch of the second student, starts to vibrate and move towards the fourth student. In the meantime, the second student returns to their original place. The vibration continues down the line until it reaches the last student, who bangs the drum eardrum when the last air molecule reaches them.

Run through it a second time with more speed. Can sound exist in space outside of the space shuttle?
