Want this question answered?
refractive index is something that measures the speed of light as it goes through an object is the ratio between real depth(the distance from the object to the surface of the medium) and apparent depth(the distance from the virtual image pf the object to the surface of the medium) dazani ch? siri bxo zurnay leda!
Density
It is the ratio of an object's weight to its volume. Alternatively it can be said, it is the weight of the object per unit of volume.
Specific Gravity.
1 is to 1
The ratio of the height of an object to the length of its base.
Aspect Ratio If an aspect ratio of an image is changed the image will be distorted either vertically or horizontally
13.7 millimetersThis answer is correct, but the formula is most important.The formula is:Hi = height of imageHo = height of objectSi = Distance of image from lensSo = Distance of object from lensYou are trying to find Si, so that is your unknown.Here is your formula: Hi/Ho = Si/SoOr in this case: 3.5/13 = Si/51The rest is basic algebra.Good luck!You can use the ratio equation; (Image Height)/(object height) = - (image location)/(object location) In your case you will get a negative location which means the image is on the same side of the lens as the incoming light.
Aspect Ratio: The relationship of an object's height to its width.
Aspect Ratio
I think it is aspect ratio.
The size of the image depends on the aspect ratio of the theater screen.
It's a ratio of Image distance to the Object distance.
There is no weight ratio for height. The weight of an object depends on its the volume and density. The volume depends on the height as well as the average cross section so height, alone, cannot determine weight.
Not 100% sure but i believe its aspect ratio.
There is no constant ratio for image size to object size It depends on, 1. Image size 2. Sensor specifications (ex: Focal length of the camera) 3. Camera to Object distance 4. Acquisition angle (Theta) 5. Light focusing 6. Need some Known object values for determine unknown object size etc...
The ratio of the spacing of the fingers and the distance from your eye will be the same as the ratio of the height of the object to its distance from you, so Hf/Df = Ho/Do and Do = HoDf/Hf
