In Youngs double slit experiment the fring spacing can be increased by these methods. Write true or false. Correct if any statement is false.a) By decreasing distance.b) By increasing the wavelenghtc) By increasing the refractive index of the medium in which experiment is taking place (e.g. this experiment is originally done in air. This experiment can also be performed in water of higher refractive index)d) By increasing the distance between the two coherent sources.c) This experiment is not valid for other waves like Electromagnetic waves, Sound Waves
