Are each of the following statements true or false (if false, explain why). In physics, if a quantity, x, is “quantised” this means:

a. The quantity x can only take pre-defined discrete values e.g. a set of integer values 1, 2, 3... or a set of integer and half-integer values 1/2, , 11/2, 2...

b. The quantity x can only take a finite number of values e.g. 1, 2, 3, 4 or 1/2, , 11/2, 2, 21/2 not an infinite set of values.

Answer #1

a. True

      In physics, if a quantity, x, is “quantised” this means the quantity x can only take pre-defined discrete values

According to Planck's quantum thoery , although light was a wave, these waves could gain or lose energy only in finite amounts related to their frequency. Planck called these "lumps" of light energy "quanta"

these are descrete values only. E= hv ,

b)   True The quantity x can only take a finite number of values if it is pre defined to take only these perticular values only.

Which of the following statements is false? It is not possible for a continuous variable to have a finite number of values. If a random variable can take on all of the possible values between 2 and 4, then it is a continuous variable. It is possible for a discrete variable to have an infinite number of possible values. A discrete variable is always represented by whole numbers.
