Q1:
If the electric field at a certain point is zero, does the electric potential at the point have to
be zero? Marks 5
Q 2:
The LASER used to read compact disc (CD) has a wavelength of 780nm, while the
LASER used to read a DVD has a wavelength of 560nm. How does this make it possible
for a DVD to hold more information than a CD? Marks 5
Q 3:
Can sound waves undergo diffraction around an edge? Explain it. Marks 5
Q 4:
Soapy water is colorless, but when blown into bubbles it shows vibrant color. How does
the thickness of the bubble walls determine the particular colors that appear? Marks 5 :text-thankyoublue:
