(а).       Whаt is the temperаture оf a black bоdy whоse peak emission occurs at a wavelength of 9.35 x 10-6 m?                                 (1.5 points) (b).         A blackbody has a surface area of 0.978 m2. If the temperature of the black body is 1500 K, how much energy does it emit each second?                                                                                                                                                                                                          (1.5 points)
