Answers
a} Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
b} Evaporation is a normal process that occurs when the liquid form changes into the gaseous form; while causing an increase in the pressure or temperature. Boiling is an unnatural process where the liquid gets heated up and vaporized due to continuous heating of the liquid.
c} Scalars are quantities that are fully described by a magnitude (or numerical value) alone. Vectors are quantities that are fully described by both a magnitude and a direction.
d} A real image and a virtual image are different forms of image. The main difference between real and virtual images lies in the way in which they are produced. A real image is formed when rays converge, whereas a virtual image occurs where rays only appear to diverge.
e} A motion repeating itself at regular intervals is regarded as periodic motion. A motion that repeats itself is considered a non-periodic motion but not at regular periods of time.
Answer:
Time period and frequency: Frequency refers to how often something happens. Period refers to the time it takes something to happen.
The time period is defined as the smallest time interval required by a wave to complete a wave cycle whereas the number of complete wave repetitions occurring in a unit time is referred as frequency.
Evaporation and boiling: Evaporation is a normal process that occurs when the liquid form changes into the gaseous form; while causing an increase in the pressure or temperature whereas boiling is an unnatural process where the liquid gets heated up and vaporized due to continuous heating of the liquid.
Scalar and vector quantity: Scalars are quantities that are fully described by a magnitude alone. Vectors are quantities that are fully described by both a magnitude and a direction.
Real and virtual image: The main difference between real and virtual images lies in the way in which they are produced. A real image is formed when rays converge, whereas a virtual image occurs where rays only appear to diverge.
Periodic and non-periodic motion: A motion repeating itself at regular intervals is regarded as periodic motion. A motion that repeats itself is considered a non-periodic motion but not at regular periods of time.
