According to wave mechanics, a free particle in space can poSsess energies of the following type (A) DisCrete energies (C) Both types of energies (B) Continuous energies5 (D) Only one single value of energy
according to wave machanics partice have continues energy because waves are continuous and every part of wave radiate means have energy ie. wave have continuous energy distribution...
option b is correct as according to quantum mechanics, free particle in space possess continuous energy but if the system is bounded , then free particle possess discrete energy.
