The diagram shows light interacting with an object. Which object is the light most likely striking?
2 answers:
a window
Explanation:
The diagram attached that shows light interacting with an object shows that the object is most definitely a window.
The window must have been made up of glass.
- The wave path completely describes refraction of waves as they cross the boundary between two medium.
- The light moves from a less dense to a denser medium and this causes the velocity to slow down.
- On coming from the other side, the wave rays are attenuated.

Answer:
The pH value of the mixture will be 7.00
Explanation:
Mono and disodium hydrogen phosphate mixture act as a buffer to maintain pH value around 7. Henderson–Hasselbalch equation is used to determine the pH value of a buffer mixture, which is mathematically expressed as,
According to the given conditions, the equation will become as follow
The base and acid are assigned by observing the pKa values of both the compounds; smaller value means more acidic. NaH₂PO₄ has a pKa value of 6.86, while Na₂HPO₄ has a pKa value of 12.32 (not given, but it's a constant). Another more easy way is to the count the acidic hydrogen in the molecular formula; the compound with more acidic hydrogens will be assigned acidic and vice versa.
Placing all the given data we obtain,
