Do you see a connection between wavelength and frequency? Explain.
katrin2010 [14]

Answer:

Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

Amplitude is the height of a wave which is the brightness of a light or loudness of a sound. So Frequency and Amplitude though are part of a wave are not dependent on each other. Their is no relation between frequency and amplitude.

hope it helps

ankoles [38]
<h2 /><h2>Answer-</h2>

The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory (1991–2000), the Chandra X-ray Observatory (1999–present), and the Spitzer Space Telescope (2003–2020). The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft.

What is it called when the forest remains but its richness and well-being have deteriorated?
ira [324]

Answer: Biodiversity loss

Explanation:

The biodiversity can be defined as the variety of life forms on earth or any other region. The forests are rich sources of biodiversity. The hunting, poaching, animal trafficking, and other ill-legal related human activities are like to reduce the species richness in forests. As many species are dependent upon other species for food, mate and other requirements for completing the life cycle thus the well-being of the forests will get deteriorated by the loss of biodiversity.
