There were several custom labels, also, such as Leon Russell's Carney see below and J. Cale's Really. These custom labels used a new logo without the "superman" emblem, with just a shakily hand drawn "S" inside an egg-shaped oval. When Shelter switched to MCA for distribution, a new label was designed. When ABC took over distribution, they initially used an orange label with orange print, with similar design to the MCA label, but with a small ABC logo at the right of the center hole.
What are the advantages of a diffraction grating over a prism in dispersing light for spectral analysis? Can the lines in a diffraction grating be too close together to be useful as a spectroscopic tool for visible light?
If so, what type of EM radiation would the grating be suitable for? If a beam of white light passes through a diffraction grating with vertical lines, the light is dispersed into rainbow colors on the right and left. If a glass prism disperses white light to the right into a rainbow, how does the sequence of colors compare with that produced on the right by a diffraction grating?
Suppose pure-wavelength light falls on a diffraction grating. What happens to the interference pattern if the same light falls on a grating that has more lines per centimeter? What happens to the interference pattern if a longer-wavelength light falls on the same grating?
Explain how these two effects are consistent in terms of the relationship of wavelength to the distance between slits. Suppose a feather appears green but has no green pigment. Explain in terms of diffraction. It is possible that there is no minimum in the interference pattern of a single slit.
Explain why. Is the same true of double slits and diffraction gratings? At what angle will the first-order maximum be for nm-wavelength green light? Find the angle for the third-order maximum for nm-wavelength yellow light falling on a diffraction grating having lines per centimeter. How many lines per centimeter are there on a diffraction grating that gives a first-order maximum for nm blue light at an angle of What is the distance between lines on a diffraction grating that produces a second-order maximum for nm red light at an angle of Calculate the wavelength of light that has its second-order maximum at An electric current through hydrogen gas produces several distinct wavelengths of visible light.
Indeed nice the way you teach is excellent. Thank you so much for such useful knowledge. Your name. Plain text. So a line would look like this. And to show that it keeps on going on forever in that direction right over there, we draw this arrow, and to keep showing that it goes on forever in kind of the down left direction, we draw this arrow right over here.
So obviously, I've never encountered something that just keeps on going straight forever. But in math-- that's the neat thing about math-- we can think about these abstract notions. And so the mathematical purest geometric sense of a line is this straight thing that goes on forever. Now, a ray is something in between. A ray has a well defined starting point. So that's its starting point, but then it just keeps on going on forever.
So the ray might start over here, but then it just keeps on going. So that right over there is a ray. Now, with that out of the way, let's actually try to do the Khan Academy module on recognizing the difference between line segments, lines, and rays.
And I think you'll find it pretty straightforward based on our little classification right over here.
