Field of View - PRACTICE FOR TEST

Front

What is the field of view in microscopy?

Back

The field of view is the visible area seen through the microscope eyepiece, which varies with different objective lenses.

Front

How does magnification affect the field of view?

Back

As magnification increases, the field of view decreases, meaning you see a smaller area but in greater detail.

Front

What is the formula to estimate the size of an object using the field of view?

Back

Estimated size of the object = (Field of view diameter) / (Number of times the object fits across the field of view).

Front

What is the typical ocular lens magnification in microscopes?

Back

The typical ocular lens magnification is 10x.

Front

What is the relationship between objective lens magnification and field of view?

Back

Higher objective lens magnification results in a smaller field of view.

Front

What is the field of view at low power if it is 3000 µm?

Back

The field of view at low power is 3000 µm.

Front

If the low power objective is 4x and the high power objective is 40x, what is the ratio of their magnifications?

Back

The ratio of their magnifications is 1:10.

Front

What is the estimated size of an object if the field of view is 200 µm and the object fits twice across?

Back

The estimated size of the object is 100 µm.

Front

What type of objective lens provides the smallest field of view?

Back

The high power objective provides the smallest field of view.

Front

If the field of view is 800 µm at medium power, what would it be at low power (4x)?

Back

The field of view at low power would be larger than 800 µm, typically around 3000 µm.
