<span>A negative space is the space around and between the real object. It is the space that forms around the subject after it has altered to give an artistic feel. A dark energy is hypothesized to infuse all of space accelerating the expansion of the universe. It is also an unknown form of energy. A black hole exhibits a strong gravitational pull that no astronomical object can escape from it. A dark matter is a black space in the universe that constitutes most of the unknown. They so not emit light at any wavelength. The answer is letter D.</span>

Calculate the wavelength of a photon having 3.26 x 10^-19 joules of energy
bekas [8.4K]
The energy of a photon is given by:
E=hf
where h is the Planck constant and f is the photon frequency.
We know the energy of the photon, E=3.26 \cdot 10^{-19} J, so we can rearrange the equation to calculate the frequency of the photon:
f= \frac{E}{h}= \frac{3.26 \cdot 10^{-19}J}{6.6 \cdot 10^{-34}Js}=4.94 \cdot 10^{14}Hz

And now we can use the following relationship between frequency f, wavelength \lambda and speed of light c to find the wavelength of the photon:
\lambda= \frac{c}{f}= \frac{3 \cdot 10^8 m/s}{4.94 \cdot 10^{14} Hz}=6.07\cdot 10^{-7} m=607 nm
