1) E=c/wavelength (change to meters)
2) E(in J)=hv
3) E(in J) x (6.022x10^23) x 2 mol
4) Do your final conversions ( IF THEY ASK FOR A UNIT OTHER THAN JOULES)

In double slit interference for a wavelength of 500nm the path length difference between the two waves for the second constructive interference fringe is?
1 micrometer (1,000 nm)
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.
Contrast the way light microscopes and electron microscopes magnify objects?
Sample illumination is achieved in different ways in a light and electron microscope.In a light microscope, the sample is illuminates with light (photon energy)In an electron microscope, the sample is illuminated by a beam of electrons.Devon
What wavelength of visible light is least utilized by chlorophyll?
White absorbs the least light. The "pigment" that causes the color white does not absorb any other colors, so all the colors are reflected back to you as "everything", or white. Think of white light. There are many colors hidden in white light, and by the process of refraction, white light can be separated and a rainbow of colors revealed. Black, on the other hand, is a pigment that absorbs all colors of light. Since no color is present, what you see is essentially a reflection of "nothing".
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.
What color corresponds with 500nm?
Blue
What happens blue light passes through a blue filter?
425-500nm
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).
In double slit interference for a wavelength of 500nm the path length difference between the two waves for the second constructive interference fringe is?
1 micrometer (1,000 nm)
What is the frequency of light in fused quartz if the wavelength in vacuum is 500nm?
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.
What is the size of a lysosome?
They vary in size between 0.1 - 1.2 micrometres.
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 wavelenght of light make the leaves green?
Chlorophyll is a green pigment found in most plants, algae, and cyanobacteria. Its name is derived from the Greek chloros "green"andphyllon "leaf". Chlorophyll absorbs light most strongly in the blue and red but poorly in the green portions of the electromagnetic spectrum, hence the green color of chlorophyll-containing tissues such as plant leaves.Green on the visible light spectrum exists between the wavelengths of 500nm and 550nm
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.
