Explain the Diagramming Waves?
There are two ways that waves can be indicated in a two-dimensional diagram. Parallel lines can be drawn that are meant to show the position of the peak displacement of the waves. This method is most commonly used to show water and sound waves, but it also is used for light, especially when we start talking about interference and diffraction.
Alternatively, rays may be drawn perpendicular to these wavefronts, indicating the direction of travel of the waves. Reflection of waves from a flat surface requires that the angle of incidence, θi (measured from the incoming ray to the normal of the reflective surface) must equal the angle of reflection, θr (measured from the normal to the reflected ray).
Q. Define: ionisation potential? The ionisation potential is that increase speed potential which makes the impinging electron acquires sufficient energy to knock out an electro

How to calibrate an oscilloscope?
POSITIVE ACCELERATION: If velocity of a body is enhancing, then its acceleration is said to be positive. The direction of positive acceleration is similar as that of velocity.
Can we take a negative test charge to find electric field?
As a longitudinal wave moves through a medium, the particles of the medium: w) Vibrate in a path parallel to the path of the wave x) Vibrate in a path perpendicular to t
