A diffraction pattern is obtained using a beam of red light. What happens if the red light is replaced by blue light?

In Young's double-slit experiment, the angular width of a fringe formed on a distant screen is $$1^o$$. The slit separation is 0.01 mm. The wavelength of the light is  

Young's expt. the ratio of intensity at maxima and minima in the interference pattern is The 25 : 9. The ratio of slit width will be

Young's double slit experiment is carried out by using green, red and blue light, one color at a time. The fringe widths recorded are $$\beta_{G}, \beta_{R}$$ and $$\beta_{B}$$, respectively. Then

For minima to take place between two monochromatic light waves of wavelength $$\lambda ,$$ the path difference should be

The ratio of resolving power of telescope, when lights of wavelength $$4000\overset{o}{A}$$ and $$5000\overset{o}{A}$$ are used, is _________.

In the case of linearly polarized light, the magnitude of the electric field vector

To increase the magnification of a telescope 

The phenomena which is not explained by Huygen's construction of the wavefront

When two waves with same frequency and constant phase difference interfere,
