The specific wavelengths of light seen through a prism that are made when a high voltage current is passed through a tube of hydrogen gas at a low pressure is a?
photoelectric effect
Wavelengths of violet light compared to wavelengths of ultraviolet light?
Violet light has longer wavelengths.
Do short wavelengths have a higher velocity than long wavelengths?
No.
What is the separation of light into different wavelengths?
It means the wavelengths are separated. White light, for example, is actually a mixture of different wavelengths.
Electromagnetic waves whose photons carry the highest energy also have the:?
shortest wavelengths
What is a hydrogen filter for a telescope?
A filter to let through certain wavelenghts of light. The wavelengths that Hydrogen is most active in. Other light does not get through so objects that "shine" in those wavelengths do not show in the image.
What is revealed by observing the sun at a very narrow range of wavelengths within the 656 nm hydrogen alpha line?
the structure of the chromosphere
Is hydrogen light a monochromatic source?
NO. It produces four lines with wide difference in wavelengths. So it is not a monochromatic just as sodium vapour lamp
How do you demonstrate the red shift and Doppler effect?
Examine the light of hydrogen emissions from a distant galaxy. Compare that spectrum with that of hydrogen in a laboratory. You'll find that spectrum is identical EXCEPT that it is shifted towards longer wavelengths.

Wavelengths of violet light compared to wavelengths of ultraviolet light?
Violet light has longer wavelengths.
The absorption spectrum of a hydrogen atom contains dark bands at specific wavelengths The emission spectrum of a hydrogen atom contains bright bands at the same wavelengths Explain what causes ther?
The short answer is these bands represent the (frequency) wavelengths which correspond to orbital configurations for the atom (matter). Absorption is used to identify chemical bonds of elements & compounds by radiating a substance across a range of frequencies & measuring the magnitude of the signal at these frequencies in chemical analysis of a sample. Emission is based upon the same principle except that the substance is heated to the point that it emits radiation (light).
What are color wavelengths?
The longest visible wavelengths are red,
How would you describe the wavelengths of incoming solar radiation compared to the wavelengths of reradiated heat?
The wavelengths of incoming solar radiation are shorter than the wavelengths of reradiated heat.
What is the Balmer Series?
The Balmer series is a section of the hydrogen atomic emission line spectrum. They show the wavelengths of light emitted when electrons transition back to the n = 2 quantum level.
How long are X-ray wavelengths compared with ultraviolet wavelengths?
Ultraviolet photons have wavelengths below 400nm. X-ray photons have wavelengths between 0.01nm - 10nm. Photons with wavelengths smaller than xrays' are called gamma rays.
Do short wavelengths have a higher velocity than long wavelengths?
No.
