Wavelength= 1/wavenumber\n\nWavelength= 1/1700cm-1\nWavelength= 5.882 x 10^-4 cm\nWavelength= 5882nm

The wave length is the distance between two  consecutive points which are in same phase.\n\nThe wave pattern repeats itself after one wavelength.\n\nThus we can consider this as one cycle of operation. \n\nOne cycle corresponds to 2pi radian or 360 degree.\n\nThus a wave length ( Lambda) corresponds to 2pi radian\n\nAny orbitrary length l corresponds to( 2 pi/ lambda ) x l\n\nThe path differnce l is equivalent to a phase difference of  ( 2 pi/ lambda ) x l\n\nA phase difference of Theta corresponds to a path difference of  ( Lambda/2pi ) x theta.

Speed of waves = wavelength X frequency of waves.

Assuming the speed of sound in air to be 334 m/sec., and using the formula,\n\nwavelength = speed/frequency,\n\nThe longest wavelength for a human with average hearing capacity (20 Hz to 20,000 Hz) = 334/20=16.7 metres.\n\nThe shortest wavelength would be 334/20000=0.167 metres=16.7 cm\n\nThus, the wavelength limits (as per the average human audibility range) are from about 17 cm to 16.7 metres.

I think you're talking RF not audio and the given C value sounds just fine. We pretty much agree except for the decimal point, unless you are using a comma for the d.p.\nI get f = v/lambda = 299792458/5.7 = 5.259517E+07 Hz, \nw = 2*pi*f = 3.304652E+08 rad/s, and \nL = 1/(w^2*C) = 1/(1.092072E+17*1.9E-12) = 4.819422E-06 H or 4.819 uH.

wavelength = speed of light/frequency\n\nwavelength = (299792458[m/s] / 100000000[1/s])\nwavelength = 2.99792458m

wavelength = speed/freqency \n=> (3 x 10^8)/(10^15)\nSo that is 3 x 10^-7 m\nor 3000 angstrom

You mean a 'frequency of 5.10^12Hz'\n\nCan you work it out yourself?:\n\nRemember that the speed (v) of the wave is 3×10^8 m/s,\nand that the wavelength is given by v/f\n\n[Edit: Darn, Kirchwey - don't do Glow's homework for her! ;-) ]

wavelength = speed of light / frequency\nfrequency = speed of light / wavelength\nf = (3*10^8 m/s) / (615*10^-9 m)\nf = 4.878*10^14 Hz\n\nwavelength = planck's constant * speed of light / energy\nenergy = planck's constant * speed of light / wavelength\nE = (6.626*10^-34 J*s) * (3*10^8 m/s) / (615*10^-9 m)\nE = 3.232*10^-19 J

frequency = C / wavelength.  c is speed of light

Electromagnetic waves move at a fixed speed, the speed of light: 299,792,458 metres per second.\n\nFor example, lets say the speed of light is 1 m/s and a length of string represents a how far the wave has travelled in a second... 1 meters.... it doesn't matter what the frequency is that's as fast as it can go.\n\nThe higher the frequency (more cycles), the shorter the wavelength in the 1 meter length of string.\nso\n1 hz = 1 wavelength per meter (wavelength = 1 m)\n2 hz = 2 wavelengths per meter (wavelength = 0.5 m)

c = lambda x nu\n\nc is the speed of light 3.0 x 10^8 m/s\n\nlambda is the wavelength\n\nnu is the frequency

f = v / lambda -> lambda = v / f\n\nv = velocity\nf = frequency\nlambda = wavelenght\nv in vacuum = c = 3 x 10^8 m/s\n\nlambda = 3 x 10^8 / 6 x 10^14 = 0.5 x 10^-6 m= 500 x 10^-9 m = 500 nm

The equations involved are:\na) freq*wavelength = velocity of wave\nb) energy of radiation E = h*freq, where h is Plank's constant.\nYou can work out from these that the choice should be a.

According to the data given\nv= 340 m/s\nf = 28 waves.sec,\nv=fλ \n340=28λ\nAnd Hence\nλ=12.14 m to .08 m

Violet is the purple part of the electromagnetic spectrum. It has a wavelength of 430 to 380 nm and a frequency of 700 to 790 THz.\n\nThese value average out at 405 nm and 745 THz.\n\nIf you square root these values, you get approximately 20.12 nm and 27.29 THz.\n\nA wave of wavelength 20.12 nm is in the Extreme UltraViolet range. A wave of frequency 27.29 THz is in the Moderate InfraRed range.\n\nSo the two answers for the square root of purple are EUV and MIR.

The refractive index will be (sin50/Sin 35)Please put the values yourself as I donot have a scientific calculator
