You are using a hydrogen discharge tube and high quality red and
blue light filters as the light source for a Michelson
interferometer. The hydrogen discharge tube provides light of
several different wavelengths (colors) in the visible range. The
red light in the hydrogen spectrum has a wavelength of 656.3 nm and
the blue light has a wavelength of 434.0 nm. When using the
discharge tube and the red filter as the light source, you view a
bright red spot...
A Michelson interferometer uses red light with a wavelength of 656.45 nm from a hydrogen discharge lamp. How many bright-dark-bright fringe shifts are observed if mirror M2 is moved 1.7000 cm ?
1. An experimenter uses a Michelson Interferometer to measure one wavelength of blue light emitted by helium atoms. Mirror 2 is moved by computer until 15,000 new bright central spots have appeared. In total, it is moved by 3.3536 mm. What is the wavelength of the light?
An important experimental device that uses interference is the Michelson interferometer. Michelson interferometers are used to make precise measurements of wavelengths and of very small distances. A Michelson interferometer takes monochromatic light from a single source and divides it into two waves that follow different paths. Interference occurs when the two light waves are recombined. The figure below shows the principal components of a Michelson interferometer. A ray of light from a monochromatic source A strikes the beam splitter C,...
400 nm Violet Blue In a discharge tube, nitrogen atoms emit light as they undergo transitions from one energy level to another that is 4.845x10-19 J lower in energy. Calculate the wavelength of the light emitted and by referring to the figure to the right, predict the color of the line in the discharge spectrum.

The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656 nm (red) and 486 nm (blue). Light from a hydrogen lamp illuminates a diffraction grating with 550 lines / mm, and the light is observed on a screen 1.2 m behind the grating.You may want to review (Page 940).For general problem-solving tips and strategies for this topic, you may want to view a Video Tutor Solution of Diffraction grating.Part AWhat is the distance between...
To measure the tiny motion of one tectonic plate relative to another, seismologists in Iceland have set up the following interferometer-like device: A laser source producing laser light with wavelength 500 nm is set up on one side of a chasm that forms the boundary between two tectonic plates. The light is split into two beams using an angled piece of glass (acting as a "beam splitter"). One part of the beam crosses the chasm and is reflected back by...
A light source containing two wavelengths, red and green, is incident on two slits separated by a distance "d". The resulting pattern is observed on a screen a distance "L"away. 1. Draw a diagram indicating the source, the slits, the screen and the resulting zeroth, first and second order pattern observed on the screen. Clearly label the color(s) of the spots. (10 Points) Op 2.

Using your spectroscope, you observe a light source and see several strong, distinct lines. Is this source continuous or discrete? Given a line with a wavelength corresponding to 500 nm, calculate the energy of the emitted light. Given a photon emitted from a hydrogen lamp with a wavelength of 434 nm, identify the correct transition in the Balmer series. R_h = 2.18 *10^(-18) J. (Hint: it is in the visible region of the electromagnetic spectrum) Looking through your spectroscope, you...
