Question
What is the phenomenon of bending of light around
corners called? ÂSolution
Diffraction is the bending of light (or other waves) around obstacles or openings.  It occurs when light encounters edges or slits, causing it to spread out.  This phenomenon is more prominent with longer wavelengths.  It is responsible for patterns of light and dark bands.
Evaluate:
√729 + √49 - √16 + 1/√64
Simplify:

(1/5)(40% of 800 – 120) = ? × 5
2/5 of 3/4 of 7/9 of 7200 = ?
`sqrt(5476)` + 40% of 1640 = ? `xx` 4 - 2020
? = (22% of 25% of 60% of 3000) + 21
Determine the simplified value of the given mathematical expression.
(342 – 20% of 5280) = ? ÷ 3
∛157464 =?
