You are watching: Is it possible to see a virtual image?
A object is inserted between a convex lens and its focal point. The photo developed isA virtual and inverted.B genuine and also erect.C virtual and erect.D genuine and inverted.
A convex lens has actually a focal size f. An object is placed in between infinity and 2f from the lens on its axis. The picture developed is locatedA in between f and also 2f.B at f.C at 2f.D between the lens and also f.
If the image distance is positive, the image developed is aA real photo.B hologram C virtual picture.D mirage
The imperiods developed by concave lensesA can be real or virtual, but always actual whenthe object is inserted at the focal allude.B are always genuine.C are always digital.D can be actual or virtual; it depends on whetherthe object distance is smaller sized or greater than the focal length.
Reflection, refractivity, and also the formation of imeras by mirrors and lenses has prospered defined by theA none of the offered answersB ray version of light.C wave design of light.D particle version of light.
An picture created once the light rays perform not actually pass with the picture location, and also would certainly not show up on paper or film inserted at that place is referred to as aA actual photo.B imaginary imageC polarized imageD virtual photo.
A convex lens has focal length f. An object is put at 2f on the axis. The picture created is locatedA between the lens and also f.B at 2f.C in between f and also 2f.D at f.
An picture formed as soon as the light rays pass through the image location, and also might appear on paper or film placed at the that place is referred to as aA imaginary imageB digital image.C actual image.D polarized image
Lenses that are thickest at the facility calledA converging lenses.B diverging lenses.C Pyrex lensesD bi-focals
A convex lens has actually a focal length f. An object isinserted between f and 2f on the axis. The photo developed is locatedA at f.B between f and 2f.C at 2f.D at a distance higher than 2f from the lens.
A convex lens has actually a focal size f. An object is put at f on the axis. The picture developed is locatedA between f and 2f.B at 2f.C at infinity.D in between 2f and infinity.
The picture of the rare stamp you view through a magnifying glass isA either the very same orientation or upside-dvery own, relying on the thickness of the glass used.B either the same orientation or upside-dvery own, depending upon how cshed the stamp is to the glass.C constantly the very same orientation as the stamp.D constantly upside-down compared to the stamp.
Is it feasible to check out a online image?A No, because the rays that seem to emanate from a digital picture do not in fact emanate from thepicture.B Yes, but just instraight in the sense that if thedigital photo is created on a sheet of photographic film, one could later on look at the photo developed.C No, considering that online images carry out not really exist.D Yes, the rays that show up to emanate from aonline image can be concentrated on the retina justlike those from an illuminated object.E Yes, considering that practically whatever we view is virtualbecause a lot of things do not themselves give off light, yet only reflect light coming from some various other source.
D Yes, the rays that show up to emanate from aonline image deserve to be focused on the retina justlike those from an illuminated object.
