Length of shadow will be more than length of object .Because light will be spread out over the screen.

answer is 2h, as light is projected from infinity, it strikes parlelly. U must take distance from the object to the screen as d and theta as the (90-incident angle) upon further solving, you’ll see that the shadow formed will be exactly twice as the height of the object(only bcoz of infinite distance)
