The depth of single high-aspect-ratio trenches and the step height of opaque materials can be measured. Deep trenches (50-225 μm) are measured with a white light interferometer. Shallower trenches and step height profiles are measured with a chromatic white light sensor.

How are depth measured?
Commonly abbreviated as D, depth is a measurement of how far back a three-dimensional object is. For example, measurements of an object, such as a computer monitor, are commonly measured as (D x W x H), short for Depth by Width by Height.
Is depth measured from the top or bottom?
Pull the weight out of the well. 3. Measure from the bottom of the weight to the ground level mark on your string. This is the depth of your well.
Which instrument is used to measure the depth of the ocean?
Fathometer is used to measure depth of ocean.
What is the unit of depth?
A fathom is a unit of length in the imperial and the U.S. customary systems equal to 6 feet (1.8288 m), used especially for measuring the depth of water.

Is depth a length or width?
Width (Side to Side): The distance or length of the item that’s touching or stretches across the wall. Depth (Back to Front): The distance or length it comes out from the wall and into the room. Height (Bottom to Top): The length starting from the floor and going to the top of the piece.
Does depth mean height?
Height vs Depth
Height is a measurement of the vertical magnitude of the object. Depth is also a measurement of the vertical magnitude of an object. These two terms may look like representing the same quantity. These terms are mostly intuitive, and we often overlook the definition of these terms.
What order is height width depth?
What comes first? The Graphics’ industry standard is width by height (width x height). Meaning that when you write your measurements, you write them from your point of view, beginning with the width.
Is depth measured in negative?
It should be measured from surface of the water to surface of the water in downwards. The direction of measuring in this case is opposite to the direction of the actual measuring. Therefore, the direction of measuring depth is considered as negative. So, – 20 m represents depth from the surface of the earth.
How do you know how deep your water is?
The most reliable method of obtaining the depth to the water table at any given time is to measure the water level in a shallow well with a tape. If no wells are available, surface geophysical methods can sometimes be used, depending on surface accessibility for placing electric or acoustic probes.
What is fathom used for?
fathom, old English measure of length, now standardized at 6 feet (1.83 metre), which has long been used as a nautical unit of depth.
What length is a nautical mile?
6080 feet
The ‘standard’ nautical mile is taken as 6080 feet (1.151 statute miles or 1853 metres) and is the unit of length used in sea and air navigation.
What is a fathom in depth?
Definition of fathom
(Entry 1 of 2) 1 : a unit of length equal to six feet (1.83 meters) used especially for measuring the depth of water —sometimes used in the singular when qualified by a number five fathom deep.
Is depth the same as deep?
“This part of the lake is more than 40 m in depth” or “more than 40 m deep.” 2. “This part of the pool is 10 m in depth” or “is 10 m deep.” Both forms are correct.
Is depth the same as thickness?
English – U.S. The depth of a shelf is its distance from front to back. 34cm is a reasonable depth for many types of shelves. The thickness of a shelf is its distance from top to bottom.
What is W * H * D?
What does width, height and depth mean? One of the biggest issues we hear is that people get the measurements width, height and depth mixed up. The industry standard is to display these measurements in the order of width first, height second and depth third.
What is an example of depth?
Depth is defined as the distance from top down or front to back, or the intensity of color or sound. An example of depth is a swimming pool being six feet deep.
What comes first length or width?
The first number is always the length, the second number is always the width, and the third number is always the height. This order is important to know because it will help you determine the size of the product. The reason measurements are always in this order is because that is how most things are measured.
What is depth in a square?
In the figure above, the side labeled depth is more commonly referred to as height, but if the chosen reference point is the top of the rectangular prism, then the depth is the distance measured downward from that point to the bottom of the prism.
How do measurements go in order?
Length, width, height, depth.
How are dimensions listed in order?
The dimensions displayed in the size tab are listed as length x width x height.
