Accepted Answer
Wavelength of the frequency 700 nanometer.In physics, the term frequency refers to the number of waves passing through a fixed point in unit time. It also describes the number of cycles or vibrations an object undergoes in periodic motion per unit time.Frequency is the number of occurrences of the repeating event per unit time. It is sometimes called temporal frequency when emphasizing the contrast with spatial frequency, and normal frequency when emphasizing the contrast with angular frequency.Frequency is an important parameter used in science and technology to describe the time-varying rate observed in oscillatory and periodic phenomena such as mechanical vibrations, audio signals (sound), radio waves, and light.Learn more about frequency here:- https://brainly.com/question/254161#SPJ4
