Interference of light: Wave emitted from two coherent sources having the same wavelength, equal or nearly equal amplitude when passes through a point in a medium, then superposition takes place. During superposition, if the two waves reaching the point in the same phase then the intensity will be maximum that is bright. But if the … Read more
Stationary waves: When two simple harmonic waves of the same amplitude, frequency and time period travel in opposite directions in a straight line, the resultant wave obtained is called a stationary or a standing wave. The formation of stationary waves is due to the superposition of the two waves on the particles of the medium.
Transverse waves: In transverse wave motion, the particles of the medium vibrate at right angles to the direction of propagation of wave. Example: Light waves are transverse waves. Longitudinal wave motion: In longitudinal wave motion, particles of the medium vibrate along the direction of propagation of the wave. Example: Sound waves are longitudinal waves.
Resonance: When the forced frequency is equal to the natural frequency of vibration of the body, resonance takes place. Resonance is a vibration of large amplitude produced by a relatively small vibration near the same frequency of vibrations as the natural frequency of the resonating system.
Following are various types of Audio Formats with Minimal Descriptions. MIDI (Musical Instrument Digital Interface): A MIDI file contains synthesized music. MIDI is a great choice for web, because the files are small in size. MIDI files are typically created using computer-based sequencing software or sometimes a hardware-based MIDI instrument or workstation, which organizes MIDI messages into one or more parallel “tracks” for independent … Read more
Web directories A web directory or link directory is a directory on the World Wide Web. It specializes in linking to other web sites and categorizing those links. Thus, in web directory, web sites are categorized by subject. Suggested Reading: What is URL? What are the types of URL? Describe them. What are the various types of … Read more
URL (Uniform Resource Locator): URL stands for Uniform Resource Locator, which is simply an address of a document on the web, more accurately, on the internet. Although a URL can look complex and long, it’s made up of four basic parts – protocols, host names, folder names and file name – each of which has … Read more
Linking or Links : Links are the ‘hyper’ part of the hypertext – that is the part user uses to jump from one HTML page to another. Links, also called anchors, mark text or images as elements that points to other HTML documents, images, applets, multimedia effects or specific places within a HTML document. Links differentiate HTML … Read more
Domain name selection guidelines: Domain name should have to be easy to remember, such as names that reflect the name of the organization. Example : The domain of T&T Firm may be like, tandtfirm.com Single letter domain names are not permitted. Example : x.com will not be a domain name. Each top level domain name is reserved for a specific purpose. … Read more
