Consider perfectly smooth glass plates shaped and oriented in the following ways (note that the plate spacings and fringe separations are greatly exaggerated). For each case, consider the interference pattern you would observe if the plates were illuminated from above with a sodium lamp. The top row is an example.

The correct answer is  interference

Explanation: The superposition, also called interference in some cases, is the phenomenon that occurs when two or more waves meet, generating a resulting wave equal to the algebraic sum of the disturbances of each wave.

the first lok sabha in 1951 had 22 women mps. the current lok sabha has 66. in the span of 54 years and 16 lok sabha elections it amounts to a three- fold increase in the number of women mps that made their way to the lower house of the parliament. from 5% in 1951, women mps constitute 12.2% of the lok sabha today. the rise in numbers has been steady through the years, both in absolute numbers and percentages. the notable exceptions have been the dip in numbers during the 6th lok sabha in 1977, the 9th lok sabha in 1989 and most recently the 14th lok sabha in 2004. the trends show a marked and steady increase from 1991 onwards to the present lok sabha. the 1991 figures show a jump from 5% in the previous lok sabha to 7% and the steady increase from thereon (except for 2004). it would be interesting to understand the factors for this watershed year and continuous rise and also the fall in numbers during 2004.

the average representation of women mps( 12.15%) is higher than the national average of women mlas in state assemblies, which stands at a dismal 9%. while the numbers have increased over the years, the percentage of women that make up the lok sabha even today is not a figure to be proud of, especially when the ideal number should be at 33% at least. we still have a long way to go.

central to the question of women’s representation in lok sabha is the appetite for women to take the political plunge and jump into the fray along with and against male candidates, getting tickets from their respective parties to contest elections and finally winning the seats that they contest. while popular perception might be that few women are willing to or have taken the political plunge, number of women contestants tells an interesting story. between 1957(the earliest data available) and 2015, the total number of women contestants has increased from 45 to 668. that is a whopping 15 fold increase in the number of women contesting. if we looked at the data for male contestants for the same years, the number has increased from 1474 to 7583, a five- fold increase. the 15 fold increase in women contestants indicates towards the growing appetite for women to enter the political fray and willingness to be part of political decision-making.
