This is a unit conversion problem. Nm (nanometer) is smaller than mm (millimeter).
1 mm = 1/10³m = 1 x 10⁻³ m
1 nm = 1/10⁹ m = 1 x10⁻⁹ m
1 m = 1 x 10⁹ nm
Hence, 2 mm = 2 x 10⁻³ m
Then we can convert 2 x 10⁻³ m to nm by multiplying with 10⁹.
Then 2 mm = 2 x 10⁻³ m = 2 x 10⁻³ x 10⁹ nm = 2 x 10⁶ nm.
Hence, the thickness of nickel is 2 x 10⁶ nm.
Answer:
Is the type of radiation with a higher frequency and energy.
Explanation:
Into the electromagnetic spectrum, there are several kind of radiation, the gamma one has the highest energy and frequency, because both characteristics are connected in a direct form.
Gamma radiation has higher energy and higher frequency among the different types of electromagnetic radiations.
Explanation:
The quantity of energy present in the photons determines the electromagnetic radiation type. Radio waves have low energy photons, while microwave photons have a bit more energy than the radio waves, infrared rays have more photons than the micro and radio waves, then followed by visible, ultraviolet, X-rays, and, the gamma-rays which is highly energetic among all.
A short wavelength means a high frequency, whereas, a long wavelength means a low frequency. In electromagnetic spectrum, the wavelength of gamma rays is shorter than all other electromagnetic rays. Hence, it has the high frequency.
