### Physics Questions and Explanations#### 4. Two-Slit Interference Pattern**Question:**What happens to the two-slit interference pattern using visible light if the distance between slits is tripled? Explain.**Answer:**When the distance between the slits is tripled in a two-slit interference experiment using visible light, the interference fringes' spacing will decrease. This is because the fringe spacing is inversely proportional to the distance between the slits.#### 5. Soap Bubble Appearance**Question:**Why is it that a very thin layer of a soap bubble (less than a wavelength of light) appears dark when viewed from above?**Answer:**A very thin layer of a soap bubble (less than a wavelength of light) appears dark due to destructive interference. When the thickness of the soap bubble is less than the wavelength of the incident light, the reflected waves from the top and bottom surfaces interfere destructively, canceling out each other and making the soap bubble appear dark.#### 6. Drinking with a Straw**Question:**How does a straw work to allow a person to drink a liquid?**Answer:**A straw works based on the principles of air pressure. When a person sucks the air out of the straw, it creates a pressure difference. The atmospheric pressure on the surface of the liquid outside the straw becomes greater than the pressure inside the straw, pushing the liquid up through the straw into the person's mouth.#### 7. Change in Entropy**Question:**How is the change in entropy defined in thermodynamics?**Answer:**In thermodynamics, the change in entropy is defined as the measure of the amount of disorder or randomness in a system. It can be quantified for a reversible process by the equation \( \Delta S = \int \frac{dQ_{rev}}{T} \), where \( \Delta S \) is the change in entropy, \( dQ_{rev} \) is the infinitesimal amount of reversible heat added to the system, and \( T \) is the absolute temperature at which the heat is added.#### 8. Brewster's Angle**Question:**Draw a diagram illustrating Brewster's angle. Explain the physics concepts.**Answer:** *Explanation:*Brewster's angle is the angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface with no reflection. For light
