  1. 1.

    During an exploratory mission to the icy moon Caelum, an automated research probe detects two distinct glowing crystal clusters emitting coherent monochromatic pulses. Cluster Alpha emits radiation with a wavelength of 400 nm, whereas Cluster Beta emits radiation with a wavelength of 800 nm. Based on the fundamental relationship between electromagnetic wave properties and photon energy, which statement correctly compares the individual photons emitted by these two clusters?

    • A) Photons from Cluster Beta have twice the frequency and twice the energy of photons from Cluster Alpha.
    • B) Photons from Cluster Alpha travel at twice the speed of photons from Cluster Beta in a vacuum.
    • C) Photons from Cluster Beta carry greater energy because photon energy is directly proportional to wavelength.
    • D) Photons from Cluster Alpha have twice the frequency and twice the energy of photons from Cluster Beta.
