W orking : This is a simple function generator circuit that can produce thefollowing waveforms: square wave‚ triangular wave‚ and sinewave.The circuit’s main components are four 741 IC’s. The 741 is aop-amp IC. The first op amp in Figure is configured as anastablemultivibrator‚ which continuously generates a squarewave. Assume that C3 has no charge initially. The voltage at theinverting input is zero‚ while the voltage at the non-inverting inputis very slightly positive (a ratio of the op amp’s

1. In the lab activity‚ you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you select the GO button‚ then the train will move) If the sound source is moving then when the sound gets closer‚ the volume will increase and when the sound passes by you‚ the volume will start decreasing. 2.

ripples‚ but the waves transfers energy from one point to another. there are two major classes of waves ; mechanical and electromagnetic waves . Mechanical waves are waves that require a material medium for their propagation‚ such as water waves and sound waves. Electromagnetic waves are waves that do not require a material medium for their propagation. Examples are light rays‚ radio waves‚ x-rays and gamma rays. wave motion The particle of the medium which transfer energy move to and fro‚ or vibrate

Measuring the Speed of Sound and Air using a Pulse-Echo Technique Purpose To determine the speed of sound in air using the pulse-echo experiment procedure‚ and comparing it to the predicted speed of sound in air using the measured air temperature of the classroom. Hypothesis I believe that the speed of sound it the air will be close to that of the predicted value. According to our predicted value‚ we should expect the speed of sound in the air to be at a speed of approximately 346 m/s. Materials

British Sound Analysis: A voiceover in the film British Sounds states‚ "Sometimes the class struggle is also the struggle of one image against another image‚ of one sound against another sound. In a film‚ this struggle is between images and sounds." We as spectators are able to make connection with that statement as we watch the segments in the film unfold. As the tracking shot captures the auto assembly line‚ the diegetic sounds of the noisy machines overwhelm us. This similar technique can be

The Path of Light and Sound By: Kristin Jaskowiak The organ that gives us a sense of sight is our eyes. Of the five senses‚ our eyes allow us to learn the most about our surroundings. It is important to know the structures and anatomy that make up the eyes to gain a better understanding of how light and images are processed to become sight.
