When cobalt 60 undergoes nuclear decay it emits?
Beta Particle
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.
What type of signal does radio altimeter emits?
A Radio Wave within the RF spectrum range of 4200 - 4400 MHz
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..
What wavelength of maximum intensity does the Sun emit?
The Sun emits most of its radiation in a wavelength band between 0.1 and 4.0 micrometers (µm).
How does the frequency of radiant energy relate to the absolute temperature of the radiating source?
A low temp source emits low-frequency, long wavelength waves. A medium temp source emits medium frequency, medium wavelength waves. A high temp source emits high frequency, short wavelength waves.
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.
What determines the kind of wavelength and the amount of radiation that an object emits?
just had this on a test, the answer is Temperature
The primary reason a light bulb emits light is due to?
voltage
What has a longer wavelength the sun or radio?
The question doesn't make any sense. The sun emits radio waves.
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.
Is the light from an incandescent lamp monochromatic?
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
What is the relationship between wavelengths and temperature?
There is a relationship between the temperature of an object and the wavelength at which the object produces the most light. When an object is hot, it emits more light at short wavelengths while an object emits more light at long wavelengths when it is cold. The amount of radiation emitted by an object at each wavelength depends on its temperature.
Why don't we use visible-wavelength telescopes to locate neutron stars?
A neutron star emits most of its energy at higher frequencies.
