How can you calculate wavelength 389.0nm and 7.707x10 to the power 14 Hz?

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!

To calculate the wavelength, use the formula: wavelength = speed of light / frequency. Plug in the values: speed of light = 3.00 x 10^8 m/s, frequency = 7.707 x 10^14 Hz. Calculate to find the wavelength in meters. Remember to convert the resulting value to nanometers by multiplying by 1 x 10^9 nm/m.

Explain the relationship between the resolving power of the microscope and the wavelength of the light being used?
The resolving power of a microscope is inversely proportional to the wavelength of light being used. This means that as the wavelength of light decreases, the resolving power of the microscope increases. Shorter wavelengths can resolve smaller details, allowing for higher magnification and clearer images.
Does wavelength determine the watts of a bulb?
No, wavelength and watts are different properties of light. Wavelength refers to the color or type of light produced, while watts measures the amount of power or energy the bulb consumes to produce light. The brightness of a bulb is more closely related to its wattage rather than its wavelength.
What does resolving power of a microscope depend on?
In a light microscope the resolution of the image it can project is limited by the distance each photon travels in its wavelength. Beneath this minimum distance, the "noise" of the photon's movement along its path overwhelms any resolution the light source may otherwise provide.
Ow do you calculate amperage with watts and volts?
You can calculate amperage (A) using the formula A = W / V, where W is the power in watts and V is the voltage. Simply divide the power in watts by the voltage to find the amperage.
The wavelength of the radiation emitted by a body depends upon?
The temperature of the body. As the temperature of the body increases, the wavelength of the radiation emitted decreases, shifting towards shorter wavelengths. This relationship is described by Wien's displacement law.
What is the wavelength of an electromagnetic wave that travels at 3 x 10 to power of 8 ms and has a frequency of 60 Hz?
Using the formula speed = frequency x wavelength, we can calculate the wavelength. Wavelength = speed / frequency = (3 x 10^8 m/s) / 60 Hz = 5 x 10^6 meters.
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?
The characteristic wavelength of an electron accelerated through a potential field can be calculated using the de Broglie wavelength formula: λ = h / p, where h is the Planck constant and p is the momentum of the electron. Given the speed of the electron, momentum can be calculated as p = m*v, where m is the mass of the electron. Once the momentum is determined, the wavelength can be calculated.

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.

How do you calculate uninterruptible power supply?
You can't "calculate" it...
How many meters long is a wavelength that measures 10 to the power of 2?
A wavelength that measures 10^2 would be 100 meters long.
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.
When you calculate power what do you multiply it by?
If you know the power you do not need to calculate it by anything. And if you don't, the answer will depend on what measure you do know!
What is 3(to the 2nd power) blank to the 2nd power)?
If you have 3 to the power 2 to the power 2, without any parentheses, you have to calculate from right to left. In this case, calculate 2 to the power 2; then calculate 3 to the power (whatever the result you get). If there are parentheses, do the calculation in parentheses first.
