What are the two types of angle modulation?
Frequency Modulation and Phase Modulation
What is the meaning of 2d ECHO?
echocardiogram two dimensional i.e sound produced by reflection of sound waves
What is the difference of the y-values of two points on a line?
The difference in the y-values of two points on a line is equal to the vertical distance between those points. This difference is also known as the "rise" or the "change in y." To calculate the difference in the y-values of two points (y₁, x₁) and (y₂, x₂) on a line, you simply subtract the y-coordinate of one point from the y-coordinate of the other: Difference in y-values = y₂ - y₁ This calculation gives you the vertical distance between the two points on the line.
What is the difference between one-point and two-point perspective?
Positioning is the main difference between one-point and two-point perspectives. One-point perspective uses one vanishing point while two-point perspective uses two.
What is the distance between the two points in simplest radical form?
The distance between two points is Square root of [ (difference in their 'x' coordinates)2 + (difference in their 'y' coordinates)2 ]
What is the relation between the path difference and phase difference?
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
If two light waves start out in phase with one another but one travels two wavelengths farther than the other before they come together will the waves be in phase or out of phase when they combine?
The waves will be in phase when they combine. Two waves that are in phase have reached corresponding points in their wave cycle, regardless of the path length difference traveled. In this case, the extra two wavelengths traveled by one of the waves will not affect their phase relationship.
What is the difference between constructive and destructive interference?
Constructive interference occurs when two waves meet in phase, resulting in an increase in amplitude. Destructive interference occurs when two waves meet out of phase, resulting in a decrease in amplitude or cancellation of the waves.
Is the central fringe dark or bright?
Because the path difference or the phase difference between two waves is zero
What are coherent waves?
COHERENT WAVESWhen the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:
What is the relation between path difference and phase difference of constructive interference?
In constructive interference, the path difference between two waves is an integer multiple of the wavelength, leading to a phase difference of 0 or a multiple of 2π. This results in the waves being in phase and adding up constructively to produce a larger amplitude.
Is Magnitudes of two waves are same but phase difference is zero?
AC if the signal is of the same amplitude but out of phase yes the net product Vs time will be zero.
What is the principle of interference?
The relationship is interference is the addition of two or more wave pattern and the principle of superposition is the displacement of any point due to the superposition of wave system equal to the sum of the displacements of the individual waves at that point.
What is the identical light waves in a phase called?
Identical light waves in phase are called coherent light waves. Coherent waves have a constant phase difference between them, which allows for constructive interference and the formation of interference patterns.
Conditions for interference of sound waves?
Sound waves can interfere constructively when they are in phase (peaks and troughs align) and destructively when they are out of phase (peaks align with troughs). The interference pattern depends on the relative phase difference between the waves and their amplitudes. Interference can occur when two or more sound waves overlap in space.
What are the condition of interference of light?
For interference of light to occur, two or more light waves must overlap and superpose on each other. The waves must have the same frequency and a constant phase relationship. Additionally, the waves should be coherent, meaning they have a constant phase difference between them.
What are constructive interference and destructive interference?
Constructive interference occurs when two waves with the same frequency and amplitude align perfectly to create a wave with a higher amplitude. Destructive interference occurs when two waves with the same frequency and amplitude are out of phase, leading to the waves canceling each other out and creating a wave with lower or zero amplitude.
