Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases.
1. True: Light can be reflected if it is directed towards a mirror. A mirror that is typically made of ordinary glass and has a flat reflecting surface.
Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.
Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface such as a plane mirror.
2. True: The speed of light remains the same even if it travels from one material to another. The speed of light is 3 * 10⁸ meters per seconds and it's a constant regardless of medium of propagation.
3. True: Sound could be either soft or loud.
A soft sound typically has a low volume while a loud sound posseses a high volume. An example of a soft sound is the sound from a piano while an example of a loud sound is a train's horn.
4. False: The loudness of sound decreases as it moves nearer the observer.
The loudness of a sound is directly proportional to the square of the amplitude of the sound and as such the loudness of sound increases as it moves nearer the observer.
5. True: Echo is the term used for the sound that is reflected back to its source.

2. Banking panics and monetary contraction. ...

4. Decreased international lending and tariffs.
Answer:

The gold standard,
Decreased international lending and tariffs.
The stock market crash of 1929
Explanation:
Banking panics and monetary contraction:
A banking panic arises when many depositors simultaneously lose confidence in the solvency of banks and demand that their bank deposits be paid to them in cash.
The gold standard:
The gold standard is a monetary system in which paper money is freely convertible into a fixed amount of gold. In other words, in such a monetary system, gold backs the value of money. The U.S. Constitution in 1789 gave Congress the sole right to coin money and the power to regulate its value.
Decreased international lending and tariffs:
Many economists have argued that the sharp decline in international trade after 1930 helped to worsen the Great Depression, and many historians partly blame this on the American Smoot-Hawley Tariff Act (enacted June 17, 1930) for reducing international trade and causing retaliatory tariffs in other countries.
The stock market crash of 1929:
The Wall Street Crash of 1929, also known as the Great Crash, was a major American stock market crash that occurred in the autumn of 1929. It started in September and ended late in October, when share prices on the New York Stock Exchange collapsed.
