When taking photographs of lit objects for example headlights, stars, or lamp posts we occasionally observe the appearance of spikes (refer to image below). What causes these spiking patterns to appear for headlights? For stars? What are the possible numbers of spikes that can be found on stars or headlights? Is it possible to find a star with an odd number of points?

Students set up an investigation to model the apparent brigntness of four diferent stars. They used four identical nachlights and a dark plece of poster board. They labeled the lashights A, B. C. and D. Each Nashight had brand new bateries. The students ploced the flashlights at different distances from the poster boord. Then, the students umed on the flashlights and observed the circles of Ight that shone on the poster tboard. They ranked the crcles of Ight in order hrom most bright to least bright Distance from poster Brightness board (m) Flashlight rank 3.6 26 Which Ist is the best prediction of the order from most bright to lcast bright?

a) The star 58 Eridani is a feint but naked-eye star similar to the Sun. Suppose that you are observing this star in the night sky without a telescope. Ignoring any interstellar extinction or atmospheric absorption, approximately how many photons per second arrive at your retina? Show all steps in your calculation. Look up any required information about the star using Wikipedia. Use sensible approximations so your calculation is straightforward. For example you could consider only the region of the spectrum where the photon flux peaks. b) The Mid-Infrared Instrument (MIRI, camera and spectrograph) on the James Webb Space Telescope operates in the band 5 – 28 µm. For 58 Eridani, approximately how many photons per second can be used by this instrument? Assume that MIRI takes all the photons from the full JWST mirror. Show all steps in your calculation. Describe briefly two or three other factors which play a role in determining the sensitivity of an instrument such as MIRI?

a) To which object corresponds this spectrum to? b) What is the source of radiation for each of the two humps? c) Why does the hump on the right hand side peak at higher wavelength than the hump on the left? [Specifically, what does this tell you about the temperature for each object that the light originates from?]
. The Sun as seen from Earth has an apparent magnitude of -26 in the B-band.1. What is the Sun’s absolute magnitude (in the B-band)?2. What would its apparent magnitude be as seen from Jupiter? (Jupiter is approximately 5.2 AU from theSun.)3. At a certain distance d from a Star A, its apparent brightness is f. If we were to travel at a relativisticvelocity to a point in space which is 5 times further away, how much fainter would the star appear to us?(i.e. what fraction of its original apparent brightness would it now appear to us?)
The 305-m-diameter Arecibo radio telescope pictured in figure below detected radio waves with a 9- cm average wavelength. Hint a. What was the angle between two just-resolvable point sources for this telescope? Minimum resolvable angle was urad. b. How close together could these point sources be at the 2.57 million light-year distance of the Andromeda Galaxy? (Note: Estimated radius of the Andromeda Galaxy is about 7 x 10¹7 km.) The point sources could be as close as resolvable distance. x1015 km for minimum
I can't see the solution for step 2, it seems that it's missing. Can you repost the solution please.
Explain TWO of the applications using correct terminology and connecting it to concepts in this unit. Option #1: A soap bubble is exposed to white light, and yet you see distinct colors. Why do you see different colors? Option #2: The star Mizar is a double star that only appears as two distinct stars when resolved by a telescope. Explain why. Option #3: Why is the sky blue? Option #4: What is the importance of Photo 51 and how was it made? Option #5: Why can we see more detail using an electron microscope vs an optical light microscope? Why don't you use them in your SBI4U0 class? Option #6: The MLB uses authentication holograms on their official merchandise. What is a hologram and how is it made? Option #7: Explain how the double slit experiment demonstrates the inseparability of the wave and particle nature of light and other quantum particles.
