What can laser pointers do?
Lit up 30 years ago the laser diode is the basis of all of the world's cheap lasers.A ruby laser (depicted earlier) is a solid-state laser and emits at a wavelength of 694 nm. Other lasing mediums can be selected based on the desired emission wavelength (see table below), power needed, and pulse duration. Some lasers are very powerful, such as the CO2 laser, which can cut through steel. The reason that the CO2 laser is so dangerous is because it emits laser light in the infrared and microwave region of the spectrum. Infrared radiation is heat, and this laser basically melts through whatever it is focused upon. Other lasers, such as diode lasers, are very weak and are used in today's pocket laser pointers. These lasers typically emit a red beam of light that has a wavelength between 630 nm and 680 nm. Lasers are utilized in industry and research to do many things, including using intense laser light to excite other molecules to observe what happens to them.
What note on the piano emits the sound of 400 hz?
G sharp comes the closest!
Radioactive decay occurs when?
When a radioactive element slowly turns into another element/s when it emits various particles.
A vibrating tuning fork emits sound what is emitted by the vibrating electrons of atom?
When electrons in an atom vibrate, they emit electromagnetic radiation, which can take various forms including visible light, ultraviolet light, or other wavelengths depending on the energy transitions involved. This emission occurs when electrons move between energy levels, releasing energy in the form of photons. The specific wavelength and frequency of the emitted radiation correspond to the energy difference between the electron's initial and final states.
A helium neon laser emits light of wavelength 633 nm Light from an argon laser has a wavelength of 515 nm Which laser emits the higher frequency light?
according to the wave theory of light,we have the relation that wavelength is inversely proportional to the frequency,therefore the electromagnetic wave with the lower wavelength will have higher frequency..
The primary wavelenght of radiation emitted by earths surface are?
The primary wavelength of radiation emitted by Earth's surface is in the thermal infrared range, typically around 10 micrometers (μm). This is known as long-wave radiation, which the Earth emits as heat energy.
Why is the statement the color of an object depends on the wavelengths of light it absords inaccurate?
...because the colour of an object depends on the wavelength of light it reflects, or the wavelength of light it emits.
Star A emits a continuous spectrum of light that peaks at a wavelength of 450 nm Star B emits a continuous spectrum of light that peaks at a wavelength of 700 nm What is the ratio of the temperature?
Using Wien's displacement law, we can relate the peak wavelength to the temperature of the star. The ratio of their temperatures is approximately 700 nm / 450 nm = 1.56.
What is the wavelength of maximum intensity in sunlight?
The wavelength of maximum intensity in sunlight is around 500 nm, which is in the green portion of the visible spectrum. This wavelength corresponds to the peak of the solar radiation spectrum and is where the sun emits the most energy.
What term describes the purity of a wavelength?
Monochromaticity refers to the purity of a single wavelength in light or other electromagnetic radiation. A monochromatic source emits light at a single specific wavelength without any other wavelengths present.
What has a longer wavelength the sun or radio?
The question doesn't make any sense. The sun emits radio waves.
What is the wavelength of selenium?
The wavelength of selenium typically refers to the wavelength of light emitted by selenium when it is excited. Selenium emits light in the red part of the spectrum with a wavelength around 600-700 nanometers. This characteristic makes selenium useful in applications like photocopiers and photovoltaic cells.
In air a light source emits a wavelength of 630nm under water what will the wavelength of light be?
The wavelength of light in water can be calculated using the formula: λ_w = λ_a / n, where λ_w is the wavelength in water, λ_a is the wavelength in air, and n is the refractive index of water (approximately 1.33). Plugging in the values, the wavelength of light in water would be around 473nm.
Why does the Earth emit longer wave radiation than the Sun?
The Earth emits longer wavelength infrared radiation because it absorbs sunlight and re-radiates it as heat. The Sun, on the other hand, emits shorter wavelength radiation in the form of visible light because it is much hotter than the Earth.
Why is the sun made up of seven different colours?
It isn't. It emits every wavelength there is. The seven colors are a human invention.
How do colors tell you about the temperature of a star?
The colder a star is the longer the light waves it emits. Light wavelength is what we perceive as color.
