Which electromagnetic waves emitted from the sun produce heat? What kind of energy does an unlit match have? What is the source of all energy in the atmosphere? What makes up the sun? What gives off electromagnetic radiation? What is electromagnetic energy?
What transforms an electromagnetic wave into a mechanical wave? What waves cause back and forth motion? Where does the energy in mechanical waves come from? What affects the speed of a mechanical wave? What is common in all mechanical waves?
Examples of tracing rays through an optical system What Problem Does Ray Tracing Solve? With ray tracing, it is possible to simulate the behavior of optical wavefronts through various mediums. Ray tracing makes it possible to determine the quality of the rendered image for image-forming syste...
An electromagnetic wave , whose wave normal makes an angle of 45∘ with the vertical , travelling in air strikes a horizontal liquid surface . While travelling through the liquid it gets deviated through 15∘ . What is the speed of the e.m. wave in the liquid , if the speed of elec...
The wave form of light is actually a form of energy that is created by an oscillating charge. This charge consists of an oscillating electric field and an oscillating magnetic field, hence the name electromagnetic radiation. We should note that the two fields are oscillating perpendicular to each...
Electromagnetic waves are formed when an electric field (shown in red arrows) couples with a magnetic field (shown in blue arrows). Magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave.(Image credit: NOAA.) ...

Theelectromagnetic radiationof an object is stretched out slightlyinside a gravitational field. Think of the sound waves that emanate from a siren on an emergency vehicle; as the vehicle moves toward an observer, sound waves are compressed, but as it moves away, they are stretched out, orredsh...
When sunlight hits the solar cells that make up your solar panels, it generates DC electricity, which flows to connecting wires. The wires connect the electricity to your system's inverter (or inverters depending on your setup). The inverter contains a transformer, an electromagnetic device that...
enabling ultra-fast (µs level) stepping adjustment. Meanwhile, the θx and θy axes can be manually adjusted for deflection up to ±4°. The combination of lens adjustment and phase stepping makes it more convenient for optical path adjustment applications such as image movement and interferom...
