If the eighth bright band due to light of wavelength `lamda_(1)` and coincides with ninth bright band from light of wavelength `lamda_(2)` is young's double slit experiment, then the possible wavelength of visible light are

Then nth bright band of red light of wavelength 6750Å is coincide with (n+1)^(th) bright band of green light of wavelength 5400Å . Find the value of n .

In a biprism experiment, if the 6th bright bannd with a wavelength lamda_(1) coincides with 7th dark band with a wavelength lamda_(2) , then the ratio of the wavelengths ((lamda_(1))/(lamda_(2))) is

In a Young's double slit experiment with slit separation 0.1 mm, one observes a bright fringe at angle (1)/(40) rad by using light of wavelength lamda_(1). When the light of wavelength lamda_(2) is used a bright fringe is seen at the same at the same angle in the same set up. Given that lamda_(1) and lamda_(2) are in visible range (380 nm to 740 nm), their values are :
