The vario-ring (3) rotates or can be displaced on the stationary section (1) of the lens barrel. The vario-ring (3) is mounted on the stationary section (1) to change the focal length of vario-objective system.
What is the combined focal length of a convex lens of focal length 30 cm in contact with a concave lens of focal length 20 cm ? What is the nature of the combined lens ? View Solution A convex lens of focal length 40 cm is in contact with a concave lens of focal length...
To find the new focal length of a lens when it is immersed in water, we can use the lens maker's formula. Here’s a step-by-step solution:Step 1: Understand the given data - The refractive index of the lens (μ2) = 1.5 - The re
Homework Statement The nickel's image in the figure below has twice the diameter of the nickel when the lens is 2.90 cm from the nickel. Determine the...
Focal length of a spherical lens is equal to half of its radius of curvature. It is positive for the convex lens; however, the focal length of a concave lens is negative. According to the sign convention, the image and object distanc...
Consider a makeup mirror that produces a magnification of 1.7 when a person's face is 14 cm away. What is the focal length of the makeup mirror in meters? A woman looking in a makeup mirror sees her face at twice its actual size and...
Our study suggests a negative response of commuting brown long-eared bats to ALAN, indicating that suitable daytime roosts in the centre of villages or towns may be less accessible to brown long-eared bats and other bat species, and that attic-roosting bats may have problems reaching their dark...
This customer is likely to infer from her experience that the firm regards customers’ interests as central. Therefore, we hypothesize the following: H1: A firm’s customer orientation has a positive effect on perceived customer centricity. Beyond the organizational level, customer orientation has ...
The tumors were variable in their expression pattern of CD4 and CD8, with some tumors consisting predominantly of double-positive cells and some of a mixture of double-negative, double-positive, and CD4 or CD8 single-positive cells (Figure 5c). Figure 5. Flow cytometric analysis of tumor ...
However, a high level of trust intensifies the negative effect of heightened CIC on the supplier’s new product performance. As CIC increases beyond the threshold, coordination complexities can hinder interfirm learning. A high level of trust is often accompanied by positive affect toward the partner...
