Part1 First we know that the definition for refractive indexn isn cvwhere c is the speed of light in a vacuum and v is the speed oflight in the material with that refractive indexso we see that because glass has a higher refractive index thanair we need to 1 increase c or 2 decrease vwell c is constant so we see that velocity of a wave mustdecrease when entering a medium with a higher refractive indexsuch as airtoglassnext we know that the definition of velocity v isv frequency wavelengthfrom this we see that frequency must remain constant as otherwisethere will be discontinuity between mediums for See Answer
