A wave with low energy will also have long wavelengths and low frequencies.
The given in a single photon of a wave is given by Planck's equation:
E = hc/λ
and
E = hf
Where λ is the wavelength and f is the frequency of the photon. This means that energy is directly proportional to the frequency and inversely proportional to the wavelength. Thus, it is visible that photons with a lower frequency and a longer wavelength will have a lower energy.
Answer:
Explanation:
The symbol of beryllium is Be. It is located in the second group on the periodic table.
Beryllium is a divalent cation with a charge of +2.
It is capable of losing 2 electrons in order to be like the noble gas He and this is a more stable configuration.
Answer:
As the axial tilt increases, then the seasonal contrast increases so that winters are colder and summers are warmer in both hemispheres. The northern hemisphere is tipped away from the Sun, producing short days and a low sun angle. What kind of effect does the earth's tilt and subsequent seasons have on our length of daylight (defined as sunrise to sunset). Over the equator, the answer is not much.
Answer:
The best-known threat comes from human pressures, driven by agriculture, residential, and commercial expansion into cactus habitats. But the worst offender, the scientists were surprised to find, is the illegal trade of cactus plants and seeds, affecting 47 percent of the threatened species. There are lots of different variations of cacti.
