Reflection and total internal reflection is different in a way that
a. total internal reflection can take place only when light travels from a rarer medium to a denser medium while reflection can take place vice-versa also.
b. the laws of reflection hold true for reflection but not for total internal reflection.
c. reflection is a man-made phenomena while total internal reflection is natural
d. reflection can take place when light travels from a rarer medium to denser medium and vice-versa but total internal reflection can take place only when it travels from an optically denser to an optically rarer medium.
