The energy of a photon can be calculated using the equation ( E = \frac{hc}{\lambda} ), where ( E ) is the energy, ( h ) is Planck's constant (( 6.626 \times 10^{-34} ) J·s), ( c ) is the speed of light (( 3.00 \times 10^8 ) m/s), and ( \lambda ) is the wavelength in meters. For a wavelength of ( 2.49 \times 10^{-5} ) nm (or ( 2.49 \times 10^{-14} ) m), the energy is approximately ( 8.03 \times 10^{-15} ) joules, which is equivalent to about 50.1 keV.

The wavelength of a photon can be calculated using the formula ( \lambda = \frac{h \cdot c}{E} ), where ( h ) is Planck's constant ((6.626 \times 10^{-34} , \text{Js})), ( c ) is the speed of light ((3.00 \times 10^8 , \text{m/s})), and ( E ) is the energy in joules. If ( 6.0 \times 10^{-14} , \text{J} ) is the energy, the wavelength ( \lambda ) would be approximately ( 3.31 \times 10^{-12} , \text{m} ) or 3.31 picometers. This wavelength corresponds to high-energy photons, such as X-rays or gamma rays.
Wavelength = (speed) divided by (frequency) = 10/0.5 = 20
Wavelength = speed/frequency = 30/10 = 3 meters

A wave with a wavelength of 10^-15 meters would have the greatest energy. This is because the energy of a wave is inversely proportional to its wavelength, meaning that as the wavelength decreases, the energy of the wave increases.

The energy of a photon is given by E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon. Plugging in the values, the energy of a photon with a 9 x 10^-8 m wavelength is approximately 2.21 x 10^-18 Joules.
Wavelength is 720 nanometers. Energy is 2.72 x 10-19 joules.

The wavelength is w = hc/E = .2E-24/4E-17 = 5E-9 meters.

To find the wavelength of the photon, you can use the formula: wavelength = (Planck's constant) / (photon energy). Substituting the values, the wavelength is approximately 1.024 x 10^-7 meters.
The energy of a photon is given by the equation E = hc/λ, where h is Planck's constant (6.63 x 10^-34 J*s), c is the speed of light (3 x 10^8 m/s), and λ is the wavelength of the photon. Plugging in the values, we find that the energy of a photon with a wavelength of 9 x 10^-8 m is approximately 2.21 x 10^-15 Joules.
