NO, a golgi apparatus can not be seen under a light microscope, it is one of the hardest organelles to see. It is not the size, but rather its lack of staining in contrast to the surrounding cell. Electron microscopes; however, pick up rather nice pictures of it. Both Scanning and Transmission can; however a transmission electron microscope (TEM) is particularly useful in viewing the multi-layers of this pancake looking organelle.

The Golgi apparatus looks like a stack of pancakes, and these stacks are called cisternae. Each cisterna is made up of a two-layer membrane surrounding a central liquid-filled area. There are usually four to eight stacks in a single Golgi complex, but in some organisms there can be as many as sixty. The number of Golgi complexes in each animal cell is typically between ten and twenty.
The Golgi apparatus is not attached to any other organelle, but floats freely in the cell. Each Golgi body has two "ends", the cis face and the trans face. The cis face is closest to the nuclear membrane and the endoplasmic reticulum, while the trans face is oriented outward toward the plasma membrane of the cell.
Yes, a golgi apparatus can be viewed with a compound or light microscope (LM). It is one of the more difficult organelles to see, and can be tricky. One of the main reasons for this, is it does not contrast in comparison to its cell surroundings like other organelles, partially due to its density and partially to its chemistry in how well it stains.

No, they can only be seen by electron microscope
yes, they are visible. Im doing a worksheet on it now. T-T
Viruses. They are smaller than the average wavelength of light and as such are not viewable unless an electron microscope is used.
sometimes the nucleus. To see the nucleus, you may have to stain the sample. Plastids (only found in plant cells) are visible too, along with the cell wall, the cell membrane, and the mitochondria.
Because light must pass through it.
An Electron Microscope is used to study the contents of a nucleus.
A scientist would use a light microscope to determine the size and shape of a cell. A light microscope uses visible light to illuminate the object being viewed. Light microscopy is used to observe the overall size and shape of a cell. An electron microscope is used to observe the structure and contents of a cell, including membrane-bound organelles.
Camillo Golgi, an Italian physician, was studying the nervous system, in 1897, when he discovered a unique cellular structure in a sample under his light microscope. Upon further investigation, he named this structure the internal reticular apparatus. In 1898, he publicly announced his discovery, and the structure was named after him, becoming universally known as the Golgi apparatus.
Golgi apparatus is absent in blue green algae because they do not grow where there is no light.
An electron microscope.
Objects viewed through a light microscope look a lot bigger.
Metal samples among others can be viewed by a light microscope. The light microscope, also known as an optical microscope, can view microorganisms.

The structure of the object and its surface characteristics, such as its texture and reflectivity, influence how it reflects light under a microscope. Substances that have a smooth and shiny surface will reflect light more effectively, while rough or opaque surfaces may scatter light, making it less visible under the microscope. An object's color and refractive index can also affect how it interacts with light when viewed through a microscope.
Objects that are smaller than the wavelength of visible light cannot be viewed in a compound microscope. This includes objects such as individual atoms or molecules.
Most organelles are very small and require a magnification greater than the x1500 available using a light microscope. An electron microscope is required for greater magnification and resolution. Therefore a small area of the slide is avalible.
