Why do we have to start with the lowest magnification to examine a new slide? a) If the light is too strong the high magnification might blind the observer b) The rotating nosepiece with the objective lenses can only be rotated in one direction c) The objectives for high magnifications are much larger, so the slide cannot be placed on the stage d) It is easier to focus on the specimen
