Lab Sheet 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‚ as it get closer to the person it will get louder and the farther away it gets it starts to fade. 2. Select the boy icon. Select the lowest pitch by selecting

CIRCUITS LABORATORY EXPERIMENT 3 AC Circuit Analysis 3.1 Introduction The steady-state behavior of circuits energized by sinusoidal sources is an important area of study for several reasons. First‚ the generation‚ transmission‚ distribution‚ and consumption of electric energy occur under essentially sinusoidal steady-state conditions. Second‚ an understanding of sinusoidal behavior makes possible the prediction of circuit behavior when nonsinusoidal sources are used through the use of techniques

High Frequency communication refers to radio communication in the range of frequency between 3-30 MHz or 3 000 000 – 30 000 000 Hz. The wave length range of High Frequency is 10-100 meters The Higher the frequency the shorter the wave length. High Frequency belongs to the radio portion of the electromagnetic spectrum. When electric current is sent back and forth through a wire an electromagnetic wave is created which can be amplified and transmitted out through an antena. It can then be received

Digital multimeter THEORY Lissajous patterns are formed when you combined periodic waves moving back and forth with periodic waves moving up and down. This exhibit does this electronically allowing the visitor to control the frequency of the X and Y motions independently. The resulting
