How do instruments like Guitar, Violin, Harp create music? Curious on how the music comes from string, wind, and brass instruments? String instruments make a sound when their strings vibrate in the air. In order to understand how these instruments work you have to realize that making music is not just an art but also a science. The sound is a wave, precisely a Longitudinal wave. This means that the medium that the wave travels through oscillates – or moves back and forth in the same direction, the wave is moving. String, wind and brass instruments use special kind of wave called standing waves. A standing wave is a wave that looks like it isn’t moving. Its amplitude may change but it isn’t traveling anywhere.
Standing waves are caused by two important properties- Reflection and Interference. Reflection is what happens when a wave reaches the end of a path and then moves back along the same path. That’s what happens when you send a pulse down a rope. It reaches the end and then comes right back.When we send continuous waves down the rope that’s when interference occurs. The wave reaches the end of the rope and is reflected, but there are more peaks on the way. As the peaks pass each other, they interfere with one another, changing their sizes. At certain frequencies, the reflected waves interfere in such a way that you end up with a wave that seems to stay perfectly still, with only its amplitude changing. That’s a standing wave, and it can occur both in strings and pipes. And that’s what makes music. Standing waves with different frequencies correspond to different musical notes. Musicians make music using the frequencies of the standing wave.
Science is the knowledge that is based on experiments, observations, logic and evidence and the knowledge established on truth. Students who want to study science can pursue Associates, Bachelor’s and Master’s Degree in science. They can either go to a college or study the course content through an online degree program
Colleges offering Science Degrees
There are many institutions which help the students to learn and specialize in science studies such as Astrophysics, Organic chemistry, Biology, Thermodynamics and much more.
Online Science Degree
Online Science degrees are offered by accredited science schools to helps students learn about science through the internet.
One of the best online colleges in Alaska that offer a science degree is University of Alaska Southeast (UAS).
Benefits of pursuing online degrees:
- One of the main benefits of pursuing an online degree is that students have flexibility. They can put up a schedule which suits them the best and learn accordingly. They can switch between their jobs and their learning as they don’t have a fixed time.
- They have a significant reduction in terms of cost they pay to complete the degree due to numerous reasons.
- They are given an access to a portal where they can watch lectures, have interaction with other students and have a list of homework, assignments and other activities related to the science degree.
- They have very good networking opportunities.
- They also have Instructor-student time where they can talk about the subject more deeply.
Colleges that offer the best online degree:
Best online colleges in Idaho that offer science degree is University of Idaho.
Best online colleges in Massachusetts that offer science degree are University of Massachusetts, Northeastern University, and Holyoke Community College.
Best online colleges in Texas that offer science degree are Texas A&M University, Midwestern State University (MSU), Sam Houston State University, Texas Tech University (TTU), Texas A&M University-Commerce.
Best Online Science Degree Programs in the USA include University of Southern California (USC), Humboldt State University, University of California, Davis (UCD), University of West Florida (UWF), and Florida Institute of Technology
On successful completion of a degree in science, one should have great scientific knowledge.
They should have great observational, communication, research and evaluation skills. They have knowledge on a different number of subjects like physics, chemistry, environmental science, natural science, biology and much more.
