The biprism experiment is performed by using first the blue light of wavelength 4800 Å and then with red light. It is found that the fourth bright band of blue light coincides with the third bright band of red light. What is the wavelength of red light?

An interference pattern was made by using red light. If the red light changes with blue light, the fringes will become
