EXPLANATION
Question: What is the dimension of frequency?
- a) M⁻¹L⁰T⁻¹
- b) M⁻¹L⁻²T⁻¹
- c) M⁰L⁰T⁻¹
- d) M⁻²L⁰T⁻¹
ANSWER: c) M⁰L⁰T⁻¹
EXPLANATION:
The dimension of frequency is represented by the symbol "f" and is defined as the number of occurrences of a repeating event per unit of time. The correct dimension of frequency is:
c) M⁰L⁰T⁻¹
In this dimension, M represents mass, L represents length, and T represents time. Since frequency does not have any associated mass or length, the dimensions for mass and length are both zero (M⁰L⁰), while the dimension for time is -1 (T⁻¹) because the frequency is measured in cycles per unit of time.
