Short Answer

a. Green light shines through a -diameter hole and is observed on a screen. If the hole diameter is increased by , does the circular spot of light on the screen decrease in diameter, increase in diameter, or stay the same? Explain.

b. Green light shines through a -diameter hole and is observed on a screen. If the hole diameter is increased by , does the circular spot of light on the screen decrease in diameter, increase in diameter, or stay the same? Explain.

(a) The rounded spot of light display on the screen increases.

(b) The rounded spot of light display on the screen decreses.

Step by Step Solution

Step 1: Introduction

A hole diameter, often known as a PHD, is the size of a producing tool used to drill holes. As a result, the hole size diameter estimate for non-plated through holes and plated through holes differed.

Step 2: Explanation

By increasing the hole diameter, the size of both the spot on the screen will grow. The reason for this is that when the diameter grows bigger, ray glasses will take precedence over wave optics.

Step 3: Explanation

Increasing the diameter of the hole by reduces the diameter of the spot on the screen. We must address diffraction effects when the hole is close to because it is of the same order as the wavelength of light.
