What is the measure of a nanometer?
A nanometer (nm) is a unit of length equivalent to one billionth (10-9) of a meter. For comparison, a single sheet of paper is approximately 100,000 nanometers thick and a strand of DNA is 2.5 nm across.
Is nanometers the same as meters?
One nanometer is equal to one-billionth (1/1,000,000,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval. The nanometer, or nanometre, is a multiple of the meter, which is the SI base unit for length.

Is wavelength measured in meters?
The SI unit of wavelength is meter because the wavelength is a measure of distance. As a measure of speed and distance, one meter is defined as the distance covered by light travelling in a vacuum in a duration of 1/ (3 x 10 8 ) seconds.
How is light measured in nanometers?
Light is measured by its wavelength (in nanometers). It is usually characterized by the Greek symbol λ. Visible light is usually defined as having wavelengths in the range of 400–700 nanometers (nm) or one billionth of a meter.
Why is light measured in nanometers?
The size of a wave is measured as its wavelength, which is the distance between any two corresponding points on successive waves, usually peak to peak or trough to trough. The wavelengths of the light we can see range from 400 to 700 nanometers (or billionths of a meter).

What is a key determinant in a bacteria being Gram-positive? Gram-positive bacteria have a thick peptidoglycan layer. The Gram stain exploits this characteristic by using the dye combinations of Crystal violet and Iodine.
What is the distinguishing feature of dark field microscopy quizlet?
What is the distinguishing feature of dark field microscopy? Unlike bright field or phase contrast microscopy where light passes directly through the sample, dark field microscopy reflects light off of the specimen at an angle. The resulting image is an exceptionally dark background and a vibrant specimen.
What is smaller than a meter?
· A centimeter is 100 times smaller than one meter (so 1 meter = 100 centimeters).
