Change the nm into scientific notation. Since you have 389, you want to make the number between one and ten. So, you move the decimal over and make it 3.89 times 10 to the negative 7 power. Then you multiply the two together and your answer should be 299,802,300!

Explain the relationship between the resolving power of the microscope and the wavelength of the light being used?
Resolving power of microscope is inversely related to the wavelength of the light used. So shorter the wavelength, greater the resolving power.
Does wavelength determine the watts of a bulb?
The Wattage of a bulb tell you how much power (energy per second) you put into it. The energy will come out mostly as heat but obviously also light. The wavelength has the units of length and tells you what type and color of light it generates. The energy in each particle (photon) of light is dependent on the wavelength but the total power input isn't directly related. You can have both high and low input power infra red (long wavelength) and Ultraviolet (short wavelength) lamps.
Does a baseball in flight possesses wave properties If so why can you not determine its wave properties?
yes , because acc. to de-broglie every partical has dualy nature. Now: wavelength ==== plank constant/momentum, but when we calculate the wavelength of the baseball then it is very-very small and it is impossible to detect since things like interference would happen on that length scale. for eg. let- p=5kg/m: then-- wavelength=plank constant/wavelength i.e--- wave length= 1.32*10ratio the power-34 which very-very small .
Why do alpha particles ionise the gas through which they pass?
as they are of very small wavelength they have very high ionization power and very less penetrating power.
The wavelength of light used plus the numerical aperature governs?
To find resolution power of optical microscopes.
What is the characteristic wavelength of the electron when an electron is accelerated through a particular potential field if it attains a speed of 9.38x10 to the power of 6 ms?
A characteristic wavelength of an electron can be known as the DeBroglie Wavelength. It is a formula in physics which relays energy and momentum.

In the electromagnetic spectrum is determined by its wavelength?
In the visible spectrum the color is determined by its' wavelength. The energy of the quantum package is determined by the wavelength. The shorter the wavelength the more power per package.
Why is a photon with a wavelength of 1050 multiplied by 10 to the negative 9th power?
Because the wavelength is not 1050 metres but 1050 nanometres.
What is mean by cutoff wavelength .simple definiion?
It is the range of wavelength at which the energy flowing through the system begins to reduce or attenuated. In case of devices, it is the wavelength at which interruption or cessation in power takes place.
What is the wavelength of an X-ray with a frequency of 8.0 x 10 power 18 Hz?
If you divide the speed of light (in meters/second) by the frequency (in Hz), you get the wavelength (in meters).
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).

How do you calculate mi to the second power?
To be able to calculate a mi to the second power you need to
What is the de Broglie wavelength in meters of a mosquito weighing 1.60 and flying at 1.42?
The de Broglie Wavelength of a mosquito can be calculated using a specific formula. For this example, the wavelength is 2.8 to the 28th power meters.
