Divide the speed of light in a vacuum (in meters/second) by the wavelength (which you must convert to meters); that will give you the frequency in hertz. The frequency will be the same for different substances.

Does 300nanometers have a lower frequency than 500nanometers?

300nm is the "wavelength". Wavelength and frequency are related by the following equation: λ = v / f Where λ (gamma) is the wavelength, v is the speed of the wave (typically c, the speed of light (3×10^8 m/s)), and f is the frequency. So f = v / λ. So a 300nm wave, (λ = 300*10^-9 m) has a frequency of (3e8 / 300e-9) = 1e15Hz or 1,000THz. 500nm: (3e8 / 500e-9) = 6e14Hz or 600THz. See link.


Which has the greater frequency a 300 nm photon or a 500 nm photon?

frequency = 1/s c = m/s lambda = m (wavelength) c/lambda m/s/m= frequency 1/s 300,000E9mm/s / 300nm > 300,000E9nm/s / 500nm So no, the shorter the wavelength, the higher the frequency. This is why very small waves such as gamma waves are very dangerous; they have a very high frequency compared to feet long waves such as Radio waves.


In double slit interference for a wavelength of 500nm the path length difference between the two waves for the second constructive interference fringe is?

For constructive interference in a double slit setup, the path length difference between the two waves is equal to a whole number of wavelengths plus a half-wavelength. In this case, for the second constructive fringe (m=2), the path length difference is 1.5 times the wavelength: 1.5 x 500nm = 750nm.


Calculate the limit of resolution for the oil lens of your microscope Assume an average wavelength of 500nm?

Resolving power = 0.5x wavelength/ numerical aperture (n sin theta)n sin theta in most microscope have value = 1.2 and 1.4therefore:R. P. = 0.5x500nm/ 1.25 = 200nm = 0.2 microns.(conv. 1000nm = 1micron).

What is 500nm?

500nm refers to a length of 500 nanometers, which is equal to 0.0000005 meters or 5 × 10^-7 meters. Nanometers are commonly used to measure wavelengths of light and dimensions in nanotechnology.


Calculate the energy of 2.00mol of photons for 500nm?

The energy of a photon can be calculated using the equation E = hc/λ, where h is Planck's constant (6.626 x 10^-34 J.s), c is the speed of light (3.0 x 10^8 m/s), and λ is the wavelength in meters. Converting 500nm to meters (1nm = 1 x 10^-9 m) gives 5 x 10^-7 m. Plugging these values into the equation gives E = (6.626 x 10^-34 J.s * 3.0 x 10^8 m/s) / 5 x 10^-7 m = 3.9768 x 10^-19 J. Since there are 2.00 mol of photons, the total energy would be 2.00 mol * 6.022 x 10^23 photons/mol * 3.9768 x 10^-19 J/photon = 4.78 x 10^6 J.


How many waves of 500 nanometers would it take to equal 1 cm?

A 500nm wave has a wave length of 500nm. The nano- prefix means × 10^-9 → 500 nm = 500 × 10^-9 m The centi- prefix means × 10^-2 → 1 cm = 1×10^-2 m → 1 cm ÷ 500 nm = (1×10^-2 m) ÷ (500×10^-9 m) = (1/500) × 10^(-2 - -9) = 0.002 × 10^7 = 2 × 10^4 = 20,000 waves.


What is the difference between sound and visible light in their wave lenght?

The question makes little sense, but sound is a longitudinal wave, light is a transverse wave. Light avergaes around 500nm wavelength, sound audible to the human ear ranges from a few cm to 20m or so.


What is the size of a lysosome?

They vary in size between 0.1 - 1.2 micrometres.


What happens blue light passes through a blue filter?

If blue light passes through a blue filter, the light will be transmitted through the filter because the filter is designed to allow blue light to pass through while absorbing other colors of light. The blue filter selectively transmits blue light and blocks other colors of light.


What is a battle light?

A battle light is a low intensity red lamp used in warships and inside tanks, artillery, and personnel carriers during night operations. Battle light preserve night vision by two means. The lower intensity of the light helps to reduce the dilation of the iris, allowing more light to enter the eye. The second is related to the construction of the retina. The retina is composed of two types of cells, rods and cones. Cone detect color (wavelength) and intensity of light. Rods are sensitive primary to intensity and communicate shades of gray or tones to the brain. Rods work best at low light levels and are our primary means of seeing in low light (night time) conditions. Rods are most sensitive to light in the 500nm wavelength range (corresponds to the blue/cyan range) and are blind to light in the 620nm (red) range. Not being stimulated by red light, this makes red light or battle light conditions optimal for soldiers and sailors who must be able to see to perform fine detail operations and still be able to see well in the dark.
