Diffraction of light around slits forming shapes

Click For Summary
The discussion centers on whether light passing through hexagonal slits produces images that are hexagons rotated by 90 degrees. Participants clarify that the resulting images are not simply rotated hexagons. The focus is on understanding the diffraction patterns created by these slits. The original question seeks confirmation of this phenomenon, emphasizing the need for accurate visual representation in related homework. The conclusion drawn is that the images formed do not adhere to the expected rotation.

Just wanted to confirm whether or not the images formed by light shining through hexagonal slits are hexagons rotated by 90 degrees.

In the solutions, a hexagon was not rotated 90 degrees.

Anyone?
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
