О сm 30 60 90 120 150 An optical bench is set up as shown. A concave mirror with a focal length of 60 cm is placed at x = 30 cm and an object is placed at x = 0 cm. The object is first illuminated with monochromatic red light and an image is observed at a position x =xp. The object is then illuminated with monochromatic blue light and an image is observed at a position x = Xg. How do the position xg and x, compare? (A) Both XR and XB are between x=0 cm and x= 30 cm and x>xR (B) Both xp and x, are between x = 0 cm and x= 30 cm and xR =xR (C) Both x and x, are between x = 30 cm and x= 150 cm and x > x, (D) Both x, and x, are between x = 30 cm and x= 150 cm and x =xR
