They are essential tools for producing, transmitting, and capturing signals and for storing and interpreting the information contained in them.
How to use waves x noise series#
Information can be digitized (e.g., a picture stored as the values of an array of pixels) in this form, it can be stored reliably in computer memory and sent over long distances as a series of wave pulses.Īlignment agreement: Thanks for your feedback! Photoelectric materials emit electrons when they absorb light of a high-enough frequency.Īlignment agreement: Thanks for your feedback! Multiple technologies based on the understanding of waves and their interactions with matter are part of everyday experiences in the modern world (e.g., medical imaging, communications, scanners) and in scientific research. about phenomena and/or the process of development and the design and performance of a proposed process or system) in multiple formats (including orally, graphically, textually, and mathematically).Īlignment agreement: Thanks for your feedback! This activity focuses on the following Three Dimensional Learning aspects of NGSS:Ĭommunicate technical information or ideas (e.g. Identify the frequency range for human hearing, known as the audible range.Ĭommunicate technical information about how some technological devices use the principles of wave behavior and wave interactions with matter to transmit and capture information and energy.Ĭlick to view other curriculum aligned to this Performance Expectation.Convert units, such as seconds into microseconds.Give examples of ultrasound applications in technology and everyday life.Describe how sound waves can be used to measure the distance between objects.In fact, sonograms and sonar devices take advantage of a very simple physics and math relationship that enables sound waves to be used as a tool to calculate distances (distance = time x velocity).Īfter this activity, students should be able to:

While we easily and frequently control the sound volume of TVs and music players, we can also use sound's other properties to determine the health and gender of growing fetuses or to locate sunken ships on the ocean floor. Sounds are everywhere in our daily lives. Copyright © (left to right) 2004 San Pullara, Wikipedia Natural Environment Research Council 2012 Irina Igel, Polytechnic Institute of NYU
