In physics, the terms period and frequency are applied to things that repeat or "move in cycles" or "go around" or the like. The period is the amount of time (measured in seconds, minutes, etc.) it takes to perform one complete cycle of the object or thing being observed. The frequency is the rate (in cycles per unit of time) that the cycles are happening in.
The A above middle C often used as a reference in music equates to a string on an instrument vibrating at 440 cycles per second. That 440 cycles per second (or 440 Hertz) is the frequencyof the vibration of the string. It also follows that the string will complete one entire cycle of its range of movement in 1/440th of a second. The 1/440th of a second (0.00227272727... seconds) will be the period of that motion.

∙ 6y agoAll light travels at same speed in vacuum, and that speed is designated as c, or 3 x10^8 m/s..wavelength, w, is c/f where f is frequency.Since velocity c is constant the longer the wavelength, the lower the frequency

What is the relationship between the frequency of light and its color?
Lights of different frequencies are perceived as different colors.
How do you calculate the frequency of light given its wavelength?
The speed of light = the frequency X wave length.. therefore:- Frequency = The speed of light (m/s) _______________ wave Length (m) Where the speed of light : 2.9979 x 10^8 (m/s)
What is the difference between blue light and green light?
In the visible region of electromagnetic spectrum VIBGYOR, violet having highest frequency is at one extreme and red having the lowest frequency goes to other extreme. So violet with shortest wavelength and red with the longest.
What is the relation between wave length and the color of light?
Different colors have different wavelengths
What is the frequency of a blue light with a wave length of 469 nanometers?
Frequency is in cycles per unit time Wavelength is in length per cycle To convert between the two you need the speed of the wave - which for light is the speed of light - which is given in length per unit time Frequency = Speed of light/Wavelength For a wavelength of 469 nanometers Frequency is 639 Terahertz (THz) or 639,000 Gigahertz (GHz) ... rounded to 3 significant digits since the wavelength is only given to 3 significant digits
What is the difference between unltraviolet light and infrared light?
wavelength and frequency. ultravoilet light has a short wave length and therefore a high frequency, while infrared light has a longer wave length and lower frequency
What is the relationship between the frequency of light and its color?
Lights of different frequencies are perceived as different colors.
What properties of light wave determines its color?
Frequency or wave length.The relation between frequency f and wave length lof a light waveis given by; f = c/l, where c is light's speed.

What is the relation between wave length and the color of light?
Different colors have different wavelengths
What is the connection between the frequency wavelength and color of light?
Frequency = speed / wavelength. On the other hand, light of different frequencies looks to our eyes as different colors. Some frequencies - most, in fact - can't be seen at all.
What characteristics are different between visible light and the portions of the electromagnetic spectrum the are not visible?
Frequency and so wavelength
Give two differences between red yellow and blue light waves?
they travel at a different frequency.
How do you make a distinguish between UV and VIS?
The only difference, between ultra violate light and visible light, is their frequencies, UV has higher frequency than visible and since wavelength x frequency = the speed of light (which is constant at 3x108 ms-1), therefore wavelength is higher in UV. UV light is also not visible, unlike visible light! so, in summery the difference is frequency and wave length.
