Students were observing a film on Paramoecium. It underwent a process of reproduction. Teacher said it is due to cell division. But students objected and said that there was no disappearance of nuclear membrane and no spindle formation, how can it be cell division? Can you clarify?

1. Paramoecium is a unicellular organism. The division in Paramoecium occurs by amitosis. 

2. It is the simplest mode of cell division. 

3. In amitosis, nucleus elongates and a constriction appears. This constriction deepens and divides the nucleus in two daughter nuclei followed by the division of cytoplasm.

What is the minimum thickness of a thin film `(mu=1.2)` that results in constructive interference in the reflected light? If the film is illuminated w

Correct Answer - A For constructive interference in case of soap film `2mut=(n-1/2)lambda (n-1,2,3,....)` For minima thickness `t, n=1 or 2mut=lambda//2` The minima thickness of a soap bubble `t=lambda/(4mu)=500/(4xx12)=104.17 approx104nm`
