This question seems like it requires calculus, but it actually has a much more clever solution

👉 Learn how to find the inverse of a function. The inverse of a function is a function that reverses the "effect" of the original function. One important property of the inverse of a function is that when the inverse of a function is...

NSF-funded researchers at Duke University have discovered how uniquely shaped artificial or metamaterial can control the transmission, redirection and reflection of sound waves with almost perfect efficiency.

The mirror matrix (or reflection matrix) is used to calculate the reflection of a beam of light off a mirror. The incoming light beam * the mirror matrix = outgoing light beam.

Why can you see your reflection in some objects? In this video we will look at ray diagrams for reflection, refraction and colour absorption. Visible light is part of the electromagnetic spectrum. Light is a transverse wave, and travels...

This is a lecture video explaining the concepts of specular and diffuse reflection. The video discusses how light rays follow the law of reflection, where the angle of incidence is always equal to the angle of reflection. It gives...

Reflection with and without inversion caused by fixed and free ends are demonstrated. Standing wave patterns at 5 different frequencies are demonstrated. A standing wave animation is shown to understand to how standing wave patterns are...

In this video, students learn about the properties of congruence and how to determine if two figures are congruent using reflections. The video explains the concept of reflections, including how size and shape stay the same while...

👉 Learn how to determine the transformation of a function. Transformations can be horizontal or vertical, cause stretching or shrinking or be a reflection about an axis. You will see how to look at an equation or graph and determine the...

Leadership part 1/2: This video discusses the qualities of a good CEO or leader, and provides insights and advice from successful entrepreneurial leaders. The speakers emphasize the importance of having a clear vision, being accountable,...

👉 Learn how to graph a cosine function. To graph a cosine function, we first determine the amplitude (the maximum point on the graph), the period (the distance/time for a complete oscillation), the phase shift (the horizontal shift from...

What is color? What is it that determines the color of an object? Good thing we just learned about electromagnetic radiation! Especially the visible spectrum. Let's take a look.

This video explains the technical process behind the formation of images in plane mirrors, and justifies the characteristics of those images. It covers the laws of reflection, the formation of point images, and the fact that the image in...

This is a lecture video that explains how ray diagrams can be used to describe the reflection of a wave from a surface. The video begins by demonstrating how to draw an incident ray and a normal on a surface, and how to use the law of...

This tutorial teaches how to format shapes in Microsoft Excel using two methods: the tab shape format option and the right-click menu. It covers various formatting options such as fill, line, effects, text, and size, and provides...

This is a lecture presentation on the topic of reflection and refraction experiments. The presenter explains the key terms involved in the experiment and demonstrates how the changing angle of incidence affects the angles of reflection...

Lesson on Inversion vs. Eversion of the Foot and Plantarflexion vs. Dorsiflexion of the Foot and easy ways to remember each.



Hey guys! Here is a quick video on Inversion/Eversion and Plantarflexion/Dorsiflexion of the Foot....

The video is a tutorial on transformations in geometry. The speaker explains four different types of transformations: reflection, rotation, translation, and enlargement. The speaker describes how each transformation is carried out, what...
