Demonstrating Ray Diagrams

-

 In this post, we demonstrate ray diagrams using an arrayof arrows drawn on the board as the object and the camera on your phone as the screen.

(i) Convex Lens : Arrows on the board are placed inside the focal length of the lens -> Magnfied Erect image



 



(ii) Convex Lens : Arrows on the board are placed outside the focal length of the lens -> Inverted image



 



(iii) Concave Lens: Irrespective of whether you place the arrows inside or outside the focal length, you get an erect image.



 



(iv) Convex Mirror



 



(v) Concave Mirror

Visualizing standing waves in a microwave

-

  Here’s a fun little experiment that anyone can conduct at home with a chocolate bar and a microwave oven. Remove turntable from microwave (the plate that rotates) Take a chocolate bar on a plate and place it inside microwave. Heat for for 30-60 seconds on high. You will notice that the chocolate would have melted in some regions and not in others (see image above) . But don’t worry this is supposed to happen                                                  Source   A microwave works by setting up a standing wave inside it. The size of the oven is chosen so that the peaks and troughs of the reflected microwaves line up with the incoming waves and form a “standing wave”. The above is a 1D analog of a standing wave, but a 2D standing wave looks like so: And there are nodes and anti-notes in three dimensions throughout the entire oven. At...

Earth holds an elite status in the solar system

It can be casual to forget the magnificence of our planet and get lost in our tight-knit everyday lives. In the advent of a lunar eclipse (January 31, 2018 )  it is worth knowing that when it comes to eclipses, Earth holds a pristine status in our solar system.  To understand why, we need to shift our perspective a little bit and ask -”How would it be like if you were on Io (one of the moons of Jupiter) ?”                                            Image source : Deviant art The most startling thing about this experience would be that the Jupiter would appear 36 times larger than the full moon (from earth).  That’s HUGE!   Also since the moons of Jupiter lies in the same plane, you would be witnessing an eclipse every 42 hours …                   Moons - Io, Ganymede, and Callisto in solar eclipse In ...
