In the Doppler Effect Measurement activity, is the shift (redshift) the amount of milimeters that shifted to the right compared to the line in model a? Or is the redshift the new measurement between each line (after being shifted a certain amount of milimeters to the right)? Model a is a hydrogen emission spectrum with wavelengths from the right to the left are 656.3nm(red), 486.1nm(blue-green), 434 nm (violet), and 410.1 nm (violet). I measured the distance between each line by...

Consider a galaxy cluster of physical (visible) size 1.0 Mpc. What angle would this galaxy cluster subtend if situated at redshift 1.0? Redshift 5.0? Do the calculation in a matter-dominated flat universe. Express your answer in arcminutes, where 1 arcminute = (pi/180)*(1/60) radians.

Eyeglasses are often coated with an anti-reflecting coating to reduce glare in the visible part of the spectrum. Consider a 95.0-nm-thick coating applied to the lens, where we wish to reduce the glare of the blue end of the spectrum with wavelengths near 450 nm. a) If the coating’s index of refraction is smaller than that of the lens, what index of refraction for the anti-reflection coating is needed for the thinnest film possible? b) If the coating’s index of...

A) what is the frequecny of electromagnetic radiation that has a wave length of 610pm? B) the visible portion of the electromagnetic spectrum covers the range from appro. 350 to 700nm. Is the electromagnetic radiation descrided in part A visible to the eye? C) How far woulf the electromagnetic radiation descrided in part A travel in 1.0 second? I would like to know how to solve each of these questions
