Question

Which of the following is a scientific definition of Frequency? Select one: O a. The fraction of light that reaches an object that is reflected. O b. The energy used per unit time O c. The distance between crests of a wave. (Units: meter) O d. The amount of deviation between an observation and the accepted normal value of that quantity e. The fraction of light that reaches an object that is absorbed. O f. The radiation emitted by an ideal object that increases with the temperature of the object, and that is most intense at a wavelength that decreases with the temperature of the object. Og. The rate of energy transferred per unit area. O h. The fraction of light that reaches an object that is passed through the object without being reflected or absorbed. O i. The capacity to do work. J. The number of crests of a wave that passes in a unit time. (Units:cycles per second). changing with time. a spectrum of wavelengths and includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma O k. The condition in which the inputs into a reservoir are equal to the outputs from the reservoir and so the size of the reservoir is not O I. Radiation that is can travel as a wave through a vacuum and which carries energy with is as it travels. This type of radiation comes in rays

Explanation / Answer

The correct option is j) the number of crests of a wave that passes in a unit time.

Well, light is measured in wavelength or frequency and one wavelength is equal to distance between these successive waves or troughs. And frequency is the count of number of these waves passing through a defined point in a second or in unit time. since its unit is Hertz and no other option above seems to be specific , say the option a) fraction of light cant be possible, take another b) is measured in metres not applicable. So option j fits into the definition.
