Quote from a Yamaha Virago Owner's manual:
"Make sure that the motorcycle is positioned straight up when checking the oil level. A slight tilt to the side can result in a false reading. "
I expect that to apply universally for all bikes, unless otherwise specified.
No dipstick, You have to use the clear glass window on the side of the motor, it is usually located on the lower right side near the foot peg. Oil should be near the center of the window WHEN BIKE IS UPRIGHT OFF THE KICKSTAND
It is recommended to transport a glass top range upright to avoid damaging the glass or internal components. Placing it on its side or upside down can cause stress on the glass and may result in cracking or breakage during transportation.
To produce a large and upright image that is closer to the object, the magnifying glass should be placed between the object and its focal point. This setup allows for the image to be magnified and appear upright when viewed through the magnifying glass.
You check it while it is standing straight up and the correct level is 1/2 the site glass. A little over half would be ok but no more then 3/4 and you don't want to have less then 1/2. Hope This Helps.
A magnifying glass forms a larger and magnified virtual image of the object being observed. The image appears upright and is located behind the magnifying glass at the point where the light rays converge.
A test tube rack is used to stand glass test tubes upright in. Glass test tubes have round bottoms, so need a rack to keep them upright. Otherwise, they would fall over and spill their contents.

the snake at the zoo is one of them. he accidently removed the glass that dudley was leaning on that made him fall into a snakes cage. the snake slithered away after telling harry "thanks" and harry replaced the glass that trapped dudly.
Diverging lenses produce virtual, upright, and diminished images for all object positions. The virtual image is located on the same side of the lens as the object and is always reduced in size. This is due to the diverging nature of the lens, which causes light rays to spread out.
