What will be the ratio of amplitudes of the two waves?

The ratio of amplitudes of two waves having same frequency is 3:1.

What is the ratio of amplitudes?

The actual amplitude in any year, expressed as a proportion of the average amplitude taken over a long period is called the amplitude ratio. It affords a measure of departure from normal seasonal variation.

Is the ratio of amplitude of two waves is 4 is to 3 then the ratio of maximum and minimum intensity will be?

Answer: The correct answer is 49:1.

What is path length difference?

(Note the path difference or PD is the difference in distance traveled by the two waves from their respective sources to a given point on the pattern.) For point A on the first antinodal line (m =1), the path difference is equivalent to 1 wavelength.

What is the coherent source of light?

Coherent source of light are those sources which emit a light wave having the same frequency, wavelength and in the same phase or they have a constant phase difference. A coherent source forms sustained interference patterns when superimposition of waves occur and the positions of maxima and minima are fixed.

Which of the vibration is of largest amplitude?

(i) The loudness or softness of a sound is determined by the amplitude (or intensity) of the wave. In this case the amplitude of R is greater than the amplitude of other vibration modes. Hence, the vibration R will produce more sound than the other two. Louder sound corresponds to the wave of larger amplitude.

How does length affect frequency?

When the length of a string is changed, it will vibrate with a different frequency. Shorter strings have higher frequency and therefore higher pitch. Tension refers to how tightly the string is stretched. Tightening the string gives it a higher frequency while loosening it lowers the frequency.

How is interference path difference calculated?

The general formula for destructive interference due to a path difference is given by δ = (m + 1/2) λ / n where n is the index of refraction of the medium in which the wave is traveling, λ is the wavelength, δ is the path difference and m = 0, 1, 2, 3 ….

How do you calculate interference of a wave?

If the path difference, 2x, equal one whole wavelength, we will have constructive interference, 2x = l . Solving for x, we have x = l /2. In other words, if we move by half a wavelength, we will again have constructive interference and the sound will be loud.

What are coherent sources and how interference is formed?

What are Coherent Sources? Two sources are said to be coherent when the waves emitted from them have the same frequency and constant phase difference. Interference from such waves happen all the time, the randomly phased light waves constantly produce bright and dark fringes at every point.

Why are coherent sources needed for interference?

Coherent sources are mandatory for observable interference patterns because the rate of change of phase at a given point is constant for both the sources and hence maxima and minimum.

What is the ratio of interference amplitudes between two sources?

If the amplitudes are 3 x and 5 x, then the maximum amplitude of their interference is 8 x and the minimum is 2 x, making the ratio of interference amplitudes 2:8, which reduces If the amplitude ratio of two sources producing interference is 3:5, the ratio of intensities at the maximum minimum points is?

What is the ratio of maximum intensity to minimum intensity?

Two coherent sources of different intensities send waves which interfere. The ratio of maximum intensity to the minimum intensity is 25. The intensities of the sources are in the ratio [UPSEAT 2002]

What is the ratio of intensity of two coherent sources?

Two coherent sources have intensity in the ratio of 100/1. Ratio of (intensity) max/ (intensity) min is Ratio of amplitude of interfering waves is 3 : 4. Now ratio of their intensities will be

What is the maximum intensity of an interference pattern?

Two coherent sources of intensities, I1 and I2 produce an interference pattern. The maximum intensity in the interference pattern will be [UPSEAT 2001; MP PET 2001] Two beams of light having intensities I and 4I interfere to produce a fringe pattern on a screen.
