To 3 significant figures: h = 6.63*10-34 J s If you have not encountered this type of notification, take 6.63 and divide it by 10 34 times. On your calculator type 6.63, then (usually) press "exp", then type "-34". ENSURE THAT UNITS ARE CONSTANT! This is done in SI units so energy is in Joules (Nm or Kgm2s-2) and seconds, so use: * Kilogrammes for Mass * Seconds for Time * Metres for Distance A suitable conversion system: * 1 parsec = 3.086333*1016 metres * 1 light-year = 9.46728*1015 metres * 1 astronomical unit (earth-sun distance) = 1.49*1011 metres * 1 year = 31557600 seconds * 1 day = 86400 seconds * 1 imperial ton = 1016.0416 kilogrammes * 1 short (US) ton = 907.18 kilogrammes * 1 mile = 1609.283 metres * 1 foot = 0.30479 metres * 1 yard = 0.914365 metres * 1 pound (lb) = 0.454 kilogrammes Hope this helps Paul Hurley

What is the value of plancks constant?

The value of Planck's constant is approximately 6.626 x 10^-34 m^2 kg / s. It is a fundamental physical constant that relates the energy of a photon to its frequency.


What do you need to know to calculate the frequency of a wave?

wavelength since frequency =hc/lambda h=plancks constant and c=velocity of light


What is the base unit of Plancks constant?

Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds In fact Planck's constant = 6.67 x 10-34 joule.seconds.


Which dimensional formula contains speed of light plancks constant and gravity?

Such a melange of dimensions would involve length3 mass2/time4 .Not only has it no physical significance, but, fortunately for all of us,there is no such formula.

Why LED is used to determine planks constant?

LEDs (Light Emitting Diodes) are used in determining the Planck constant because they emit light at specific frequencies when electrical current is applied. By measuring the voltage needed to produce light of a known frequency, the relationship between energy and frequency can be studied, allowing for the accurate determination of the Planck constant.


If the energy of an electron is found with Energy equals hc divided by lamda which contains only positive terms how can the energy of a bound electron be negative?

The h in the hc stands for plancks constant which is 6.63 x10^-34, which is negative. :)


A photon has a frequency of 4.0 multiplied by 104 Hz?

I assume the equation you're looking for is E=hv or E=hc/lambda. h is plancks constant and c is speed of light in m/s. lambda is in metres
