```							Dear student Planck's constant, symbolized h, relates the energy in one quantum (photon) of electromagnetic radiation to the frequency of that radiation. In the International System of units (SI), the constant is equal to approximately 6.626176 x 10-34 joule-seconds.Its  relates the energy carried by a photon to its frequency. A photon's energy is equal to its frequency multiplied by the Planck constant.E = h* vDimention of Planks constant = h = ML^2 T^-1Hope this helps Good luck Cheers

```							HEY   FRIENDFOR FINDING PLANKS CONSTANT FIRST WE HAD TO KNOW ITS FORMULASO IT IS AS                E = h*v                                 h=E/vNOW,    WE KNOW THAT (V)IS FREQUENCY WHICH IS EQUAL TO THE “ RECIPROCAL OF TIME”THEREFORE,    h=E*T                          (WE KNOW THAT SI UNIT OF E=JOULE &  T =SECOND)THUS,h=JOULE  SECOND DIMENSION= ML^2T^-1I THOUGHT IT IS HELPFULBE HAPPY
