What is phase of a sine wave?
The phase angle varies from 0 to 360 degrees as the wave cycles.
What type of light has a longer wave length ultra violent or infrared?
Ultraviolet has the longer wave length Infrared has the lower wave length
In which type of wave does light travel?
All the electro-magnetic waves travel at the speed of light. Electromagnetic spectrum includes the following: * X-rays * Gamma rays * Ultraviolet rays * Infrared waves * Microwaves * Radio waves * Cosmic rays
Which relation is there between wavelength and height?
There is no relation between wave length and wave height. You can change the wave height independently from the wave length. Wave height tells you which amplitude the wave has. If you think of sound that means how loud it is. The wave length tells you the pitch or the frequency of this sound, that means high or low sound. Long wavelength means bass sound and short wavelength means treble sound.
Difference between square wave and digital signal?
A: square wave can be positive and or negative. A digital signal is a square wave but it can be of invariable duty cycles
What causes refraction of a wave as it enters a new medium at an angle angle?
If a wave enters an environment in which it changes speed, the part that enters first appears to lag-behind or lead-in-front the original. That light refracts in this way strongly suggests that it has wave properties and that its speed has to change in moving between air, glass, and water fo example.
When light is reflected does the direction of the light wave change?
Yes, the light wave goes in the direction of the angle or reflection.
Angle between transvers wave and longitunal wave?
90 degrees.
What is the angle between the normal and the surface of a mirror?
The angle between the normal and the surface of anything is by definition always 90 degrees, regardless of whether it is a mirror, a piece of concrete, a wooden plank, etc.
The law of reflection states that the angle of blank equals the angle of reflection?
The angle of reflection is equal to the angle of incidence. In the "diagram" below the line pointing up is perpendicular to the horizontal line. The horizontal line is something like a mirror. | | ____________|_________ Now if a light wave was to hit the mirror where the two lines cross then the angle of incidence is the angle between the light wave and the perpendicular line. The angle of reflection will be the same angle only in the opposite rotation to the perpendicular
What causes refraction of a ocean wave as it enters a new medium at an angle?
A wave that enters a new medium will experience interference. It is the interference that causes the observed phenomenon we observe when a wave enters a new medium.
What happens to the light wave after it stikes the mirror?
what happens when you direct light waves at an angle into a mirror
A light wave was reflected off of a mirror at an angle of 10 degrees What was the incident angle?
The incident angle to the Mirror will be 10 deG.
What is the angle that light strikes a surface?
That is known as the angle of incidence. It is measured from the normal, which is a imaginary line perpendicular to the surface at the point where the light wave contacts the surface.
Which is the definition of refraction?
The bending of a light wave as it passes at an angle from one medium to another
When light enters glass from air at an olique angle the wave crests change direction there new direction is what?
The angel of the light ray emerging is called "Angle of Deviation"
The main difference between a radio wave and a light wave is its?
Wavelength.
