In physics and optics, light rays, such as the stream from a flashlight, are simply a model of light. Although light is considered a wave with peaks and troughs, a line drawn through them at 90 degrees will produce a light ray in the direction the energy flows. Light can be reflected...
Black Hole Physicsstars: individual (Cygnus X-1X-rays: individual (Cygnus X-1We observed Cyg X-1 with {\\em RXTE} contiguously over its 5.6-day binary orbit. The source was found to be in the hard state throughout the observation. Many intensity dips were detected in the X-ray light...

The different types of waves are: mechanical, electromagnetic, and matter waves. Mechanical waves are divided into transverse and longitudinal waves. UV rays and radio waves are types of electromagnetic waves.
while light rays are refracted (pass-through) through a lens. a mirror will have only one focal point, which is in front of the mirror. a lens has two focal points, each on either side. in the table below, let us look at more differences between mirror and lens. mirror lens a ...

Types of Mirrors Plane mirrors:They are the flat mirrors which reflects light normally and reverse from left to right. The curved mirrors are classified in Convex and Concave mirrors: Convex mirrors: These mirrors bulge outwards. They reflect light rays at a wider angle near the edges as compar...
Types of Energy: There are several different types of energy that surround us every day. These include chemical, mechanical, nuclear, and gravitational energy, which are all examples of potential energy. There is also kinetic energy, such as radiant, thermal, motion, sound, and electrical energy...
The X-rays are radiated in directions sideways from this column. As a result, the luminosity of such a X-ray pulsar can significantly increase the Eddington Polars Finally, we will look at the new class of these objects in the p-y diagram. In the process of preparing this paper, it ...
