The speed of a wave = (frequency) x (wavelength) = 2.5 meters per second.
CLASS -C amplifier is having high ditortion due to which they are not used in audio frequency work
Waves longer than 1mm are considered to be in the radio spectrum, submarine communications use waves kilometers long. Some radio waves are too long to be used in communications today. There are some very good answers regarding radio and TV communication in Related Answers right here on WikiAnswers.
What kind of question is that. What resistors, what circuit are you talking about?
Groups of eight notes are known as octaves. This series of eight notes occupy the interval between, and including, two notes, one having twice or half the frequency of vibration of the other.
Technically, the airwaves are owned by the people of the United States. The 'people' of the US, through the federal government in Washington, have decided that administration of that ownership shall be given to the Federal Communications Commission, pursuant to the Communications Act of 1934 and subsequent amendments and other such appropriate laws. For technical reasons, this is to prevent multiple broadcasters from attempting to broadcast on the same wavelength, which happened early on in the infancy of broadcasting. For financial reasons, it was done to protect advertisers who depend on having their ads heard on broadcasts which are not 'drowned' by powerful transmitters which displace noise on neighboring frequencies, perhaps including that of the advertiser who paid for the ad. And for the public sake so that each time we tune into a particular frequency, we will be assured the entity we expect to find there will be there, will be able to broadcast on that frequency and listeners/viewers will be able to hear/view that broadcaster, subject only to constraints of distance from the transmitter, ability of the receiving unit and quality of the transmission and reception.
(frequency) = (speed) / (wavelength) = (15 m per sec) / (3 m) = 5 per sec = 5 Hz.
Wavelength = Velocity / FrequencyTherefore:Frequency = Velocity / WavelengthVelocity = c, the speed of light, which is 299,792,458m/s.We know the wavelength is 413nm, which is 4.13*10-7m, so our equation is:f = (3.00 * 108) / (4.13 * 10-7) = 7.259 * 1014Hz
Each colour has different wavelengths....For example: In VIBGYOR It is in the order of increasing wavelength i.e Compared to red violet is having the shorter wavelength..... The frequency and wavelength are related by the equation: In vaccum: frequency= c/wavelengthwherec is the velocity of light in free spaceWhereas in any medium,frequency= Velocity of light in that medium/wavelength So, it is clear from the formula that the wavelength and frequency are inversely proportional to each other.... As the wavelength changes with colour the frequency also changes according to that.............. If the frequency is high, the wavelength will be low and viceversa....
Each color has a different frequency and wavelength; with red having the longest wavelength and lowest frequency of all the visible colors & violet having the shortest wavelength and highest frequency of the colors humans can see.
For any wave, the speed of the wave is the product of its frequency and of its wavelength.
Because red light has minimum frequency and thus it has maximum wavelength.
At a single wavelength, it is called monochromatic
They are both transverse waves, albeit having different wavelength and frequency. I think that velocity of the waves will also be different as x-rays travel at the speed of light.
The speed of any wave =Frequency *Wavelength here, frequency =1.49*1017 Hz & wavelength=6.39 nm =6.39* 10-9 m So speed=9.52*108 m/s
Gamma rays are the waves with the shortest wavelength. The waves having highest frequency have the shortest wavelength. As gamma rays have the highest frequency starting from 10^19 and onwards so they have the shortest wavelength starting from 10^-11 and decreasing.
Visible light has the spectrum VIBGYOR. Violet is at one extreme having highest frequency and red is at the other end having least frequency. Less frequency means having longest wavelength, since wavelength and frequency are inversely related. As we go beyond violet then it is named as ultraviolet. Same way as we go beyond red, then it known as infra red. So its wavelength has to be greater than that of red. Hence longer wavelength for IR radiations. IR is what we call 'thermal' radiation, in other words, 'heat'.
