Answer: 183.8Hz
Explanation:
Given that,
wavelength of sound (λ) = 1.85 m
frequency of the sound (F) = ?
Recall that the speed of sound (V) in air is a constant with a value of 340m/s
So, apply the formula
V = F λ
340 m/s = F x 1.85 m
F = 340m/s / 1.85m
F = 183.8Hz
Thus, the frequency of the sound that is
generated is 183.8 hertz
There are different refractive errors that are common and some of them are:
- Nearsightedness (myopia) makes far-away objects look blurry.
- Farsightedness (hyperopia) makes nearby objects look blurry.
- Astigmatism can make far-away and nearby objects look blurry or distorted.
- Presbyopia makes it hard for middle-aged and older adults to see things up close
<h3>What is Refraction?</h3>
This refers to the study of light phenomena that deflects when it passes through a medium in an oblique manner to another medium of a varying density.
Hence, we can see that there are everyday examples of refraction in simple terms which occurs and some of them are:
- Glass
- Human eyes
- Ice crystals
- Pickle jar
- Microscope, etc.
Hence, we can see that your question is incomplete, so I gave you a general overview to help you get a better understanding of the concept of refraction.

Answer: Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave.
Explanation:
Wavelength refers to the length or distance between two identical points of neighboring cycles of a wave signal traveling in space or in any physical medium. ... The wavelength of a signal is inversely proportional to its frequency, that is, the higher the frequency, the shorter the wavelength.
There wouldn't be any life on Earth and no climate if it weren't for the Sun.
The spherical form of the Earth results in changes in the amount of sunlight that reaches the surface at various latitudes, giving rise to various climatic zones. Seasons are caused by the tilt of the Earth's axis of rotation in relation to the ecliptic plane.
The surface of the sun is around 6000 C hot; at this temperature, the solar mostly produces visible light. The Earth radiates infrared energy back into space to maintain its energy balance after being warmed by incoming solar radiation. The Earth's surface has an average temperature of 15 C, and at this temperature, the planet emits infrared light.
Carbon dioxide, methane, nitrous oxide, and other atmospheric greenhouse gases let solar energy to pass through but absorb infrared radiation that the planet emits back into space. This feature is not shared by other atmospheric elements like oxygen and nitrogen. These greenhouse gases re-emit infrared radiation in all directions to maintain energy balance, some of which is aimed at the Earth's surface and warms it. More greenhouse gases will increase infrared absorption and raise surface temperatures. This is comparable to how much blanket you cover yourself with at night. The blanket's thickness affects how warm you feel. The result of heat brought on by rising levels of greenhouse gases in the atmosphere is climate change.
In the course of billions of years, the Sun will continue to get hotter and brighter, rendering the Earth uninhabitable.
Additionally, all fossil fuels (coal, petroleum, and natural gas) and renewable energy are directly and indirectly derived from the sun (wind, solar, biomass, and hydroelectric).
