Speed of a Transverse Wave 01:13

3.9K

The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings and the wavelength determine the frequency of the sound produced. The strings on a guitar have different thicknesses but may be made of similar material. They have different linear densities, and the linear density is defined as the mass per length.
One of the key properties of any wave is the wave speed. Light...

Propagation Speed of Electromagnetic Waves 01:30

4.6K

Electromagnetic waves are consistent with Ampere's law. Assuming there is no conduction current Ampere's law is given as:


Consider a plane wavefront traveling in the positive x-direction as shown in figure. Over it, consider a rectangle in the xz-plane, with an area vector in the positive y-direction. The integration is performed counterclockwise around the rectangle to solve the left-hand side of Ampere's law. The magnetic field is either zero or perpendicular to the length elements except...

The Wave Nature of Light 02:12

The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Three-Winding Transformers 01:19

701

Three identical single-phase transformers can be configured to form a three-phase transformer connection, which involves high-voltage and low-voltage windings. The high-voltage windings are denoted by capital letters A-B-C, while the low-voltage windings are labeled with lowercase letters a-b-c, representing their respective phases. This notation helps distinguish between the high and low voltage sides of the transformer.
In the per-unit equivalent circuit of a grounded Y-Y three-phase...

Global Climate Change 01:50

28.8K

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Current trends in nursing include:

The changes that have shaped the profession.
Guided legislation.
The functioning of the present healthcare system.

With an increase in the aging population worldwide, it is crucial to train nurses from all healthcare settings to identify approaches that enable older adults to live independently. Nurses also provide essential care and education to manage multiple chronic conditions and ensure the elderly in long-term care receive optimal care and...
