Predict/Calculate A Famous Double Star Albireo in the constellation Cygnus, which appears as a single star to the naked eye, isactually a beautiful double-star system, as shown in $\mathrm{HGURE} 30-24$The brighter of the two stars is referred to as A (or Beta-ol Cygni), with a surface temperature of $T_{A}=4700 \mathrm{K}$ ; its companion is $\mathrm{B}$(or Beta-02 Cygni), with a surface temperature of $T_{\mathrm{B}}=13,000 \mathrm{K}$ .(a) When viewed through a telescope, one star is a brilliant bluecolor, and the other has a warm golden color, as shown in thephoto. Is the blue star $A$ or B? Explain. (b) What is the ratio of thepeak frequencies emitted by the two stars, $\left(f_{N} / f_{\mathrm{B}}\right) ?$

in the given picture, there are two stars. Ah star, Eh Star A and start be Yeah, Damn praetor of star e equals for 1000 700 Gasoline and temperature of star be equals 13,000 Calvin, let's do party Well, Blue star Blue star is be camp rated of star B is greater than temperature off star, eh? Ah, temperature off star be is greater than Pembridge it off star Hey! Ah! Frequency of blue light is grated in frequency off warm golden color Since F week F speak is directly proportionate to temperature and be his higher temperature and, uh, be his higher temperature Higher Damn Bridger did for Blue Star is be Now, let's old Barbie in, Barbie. Uh, we have, uh, f a equals five point 88 Multiply by 10 to the power, Then multiply by 4000 700 Calvin's, which is the temperature off star, which is the temperature of star, okay and f b equals and the beak off frequency emitted by ah, star be equals 5.88 Multiply by 10 to the power, then multiply by, uh, 13,000 13,000 gallons. Now let's divide. Yeah, a big frequency emitted by Star A and B frequency emitted by star Be So We have FDA divided by F B, and this equals a 5.88 Multiply by 10 to the power, then multiply by 4700 divided by 5.88 month supply by tenderly powered, then multiply by 13,000 and we have four 700 divided by 13,000. And this equals, um zero point trade six, which can be written its little point four.
