You can easily calculate average speed having time and distance given in different units of lenght eg. Group speed is 12 the phase speed. V f times lambda where.
Miles yards meters kilometers inches etc but you can also compute traveled distance having time and average speed given in different units of speed mph kmh mps yds per second etc and you can get travel time having.
B Calculate the speed of. For example what is the wavelength of a photon that has an energy of 336 10¹⁹ J. Divide the wave height by the wave period. Miles yards meters kilometers inches etc but you can also compute traveled distance having time and average speed given in different units of speed mph kmh mps yds per second etc and you can get travel time having.
