To set up a stable and clear interference pattern
What are conditions of obtaining good interference pattern give reasons?
- The two sources of light should be coherent: ...
- The light should be monochromatic: ...
- The two light sources should be of equal brightness, i.e., the waves must have the same amplitude. ...
- The two light sources should be narrow: ...
- The interfering light waves should be in the same state of polarization:
What are ways to prevent interference?
- Transmit in different places. Two transmitters can use the same frequency at the same time if they are separated. ...
- Transmit at different frequencies. Two transmitters can cover the same area and transmit at the same time if they use different frequencies. ...
- Transmit at different times.
What are the conditions for obtaining well defined and steady interference pattern?
Conditions for obtaining well – defined and steady interference pattern: The two sources of light must be coherent. The two sources of light must be monochromatic. The two interfering waves must have the same amplitude.
What is interference in gear how it is avoided?
Interference can be avoided by using a higher pressure angle . As higher pressure angle results in smaller base circle and in turn allows more of the tooth profile to be made of involute curve. Another practical way of avoiding interference is by making the tooth of the driven gear as stub.
What is the cause of interference?
Interference occurs when unwanted radio frequency signals disrupt the use of your television, radio or cordless telephone. ... The two most common causes of interference are transmitters and electrical equipment .
How can wireless communication reduce interference?
A number of techniques have been proposed for mitigating interference in cellular networks. Common methods include; power control, effective frequency assignment using intelligent techniques and intermodulation solutions . Several authors have addressed the problems of interference in the wireless networks.
What are the types of interference?
- Constructive Interference of Light.
- Destructive interference of Light.
What is the difference between interference and diffraction?
Diffraction is the result of light propagation from distinct part of the same wavefront. While interference is the result of the interaction of light coming from two separate wavefronts. The width of the fringes in case of diffraction is not equal while the fringe width in case of interference is equal.
What is the main principle used in interference?
The main principle of interference is, when two waves interfere with each other, a resultant wave of greater, lower, or the same amplitude is formed . To know more about the light waves in a detailed and engaging way, subscribe to BYJU’S – The Learning App.
What are the conditions of steady interference pattern?
Conditions for Obtaining Steady Interference Pattern:
The amplitudes of waves must be equal. i.e. the brightness of the two sources should be the same. The sources of light should be narrow. The two sources of light must be monochromatic.
What are the condition for steady state interference pattern?
The two sources of light must be monochromatic, i.e. , the light emitted is of the same wavelength. The light waves emitted by the two sources must be of equal amplitudes or the sources must be of same intensity. The two sources must be narrow. Point sources of light in the form of illuminated slits are used.
What are the conditions for distinct interference?
For distinct interference pattern to be observed, the necessary condition is that the ratio of intensity of light emission by both the sources should be: (A) $2:1$
Which gear has highest efficiency?
| No Type Efficiency Range | 1 Spur 94-98% | 2 Straight Bevel 93-97% | 3 Spiral Bevel 95-99% | 4 Worm 90-50% |

What is gear interference?
When two gears are in mesh it is possible that an involute portion of one will contact a non-involute portion of the other gear. This phenomenon is known as “interference” and occurs when the number of teeth on the smaller of the two meshing gears is less than a required minimum .
What is the condition of correct gearing is?
Explanation: The fundamental condition of correct gearing is the common normal at the point of contact between a pair of teeth must always pass through the pitch point. ... In involute system, the basic rack has straight teeth and the same can be cut with simple tools.
