How do you find the minimum wavelength?
Calculate the minimum wavelength of X-rays emitted when electrons accelerated through 30 kV strike a target. Therefore the wavelength l (= c/f) is 0.41 x 10-10 m = 0.04 1 nm (compared with some 600 nm for yellow light)….Moseley’s law.

What is the potential difference if?
Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.
How do you find the potential difference in electricity?
Multiply the amount of the current by the amount of resistance in the circuit. The result of the multiplication will be the potential difference, measured in volts. This formula is known as Ohm’s Law, V = IR.
Which Colour has minimum wavelength?
Violet
The visible colors from shortest to longest wavelength are: Violet, Blue, Green, Yellow, Orange, and Red. Therefore, Violet has the minimum wavelength.
What is the maximum potential difference between the disks?
The maximum potential difference between the disks is 3040 V.
What is the relationship between potential and potential energy?
Potential basically tells us the ability of an object to do some work . And Potential energy is the amount of energy it acquires due to that Potential difference.
What is the minimum wavelength a photon may have in order to be considered ionizing?
EURATOM Guideline (1996): Ionizing Radiation: The transfer of energy in the form of particles or electromagnetic waves of a wavelength of 100 nm or less or a frequency of 1.1015 Hz or more capable of producing ions directly or indirectly.
Which of the following has minimum wavelength?
Gamma rays has shortest wavelength in the electromagnetic spectrum.
