Free Download of JAMB'S UTME Physics Past Questions with Answers on "Waves" and "SHM"

Free Download of Jamb-UTME- Physics past questions with Answers on "Waves" and "SHM."

There have been lots of posts out there, stating 'Free Download of  UTME Physics past questions with Answers' but only questions without answers. This has prompted me to painstakingly create this pack by solving Jamb physics past questions on different topics and making them available for download free. Not only are these questions solved topics by topics, they're also solved systematically from the simplest to the hardest. It is a unique past questions pack with answers to make easy the studying of this subject.

Side Note: 'ume 91@04' in the pack implies ume 1991 question number 4.
As the description of the website displays-understanding what you know is the key- I would like to explain briefly on this two topics in physics.

Brief explanation on the topics

Waves

A wave is a means of transferring energy. We see and hear people by means of light and sound waves. Radio waves travel to aerials through the air from television transmitters. Although we cannot see light, sound and radio waves, they travel across space. light and heat energy in the form of waves reaches us from the sun after travelling across enormous distance of empty space.

The waves most commonly studied in physics is classified into mechanical and electromagnetic. A mechanical wave or sometimes called elastic waves are waves that requires material medium for their propagation . For example, sound waves in air are variations of the local pressure that propagate by collisions between gas molecules. Other examples of mechanical waves are seismic waves, gravity waves, water waves, and shock waves. An electromagnetic wave consists of a combination of variable electric and magnetic fields, that propagates through space . Electromagnetic waves do not require material medium for their propagation. Electromagnetic waves can travel through suitable dielectric media or through vacuum; examples include radio waves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

The two main types of waves can be transverse, which travels perpendiculary to the direction of vibrations and longitudinal, which travels in a direction parallel to vibrations. While mechanical waves can be both transverse and longitudinal, electromagnetic waves are transverse in free space.

Simple harmonic motion

Simple harmonic motion is the motion of an object whose acceleration is proportional to its displacement from a fixed point and is directed towards that fixed point.

In the figure above, the bob O of a simple pendulum, moving through a small angle θ, has simple harmonic motion. As it swings to-and-fro, it has an average or central position O. The maximum displacement, OA or OB, is called the amplitude of the motion. From O to A, then to B and back to O again, is called one complete cycle. The time for one cycle is called the period T of the motion. The frequency f is the number of cycles per second and is measured in hertz, Hz. Always T=1/f or f=1/T.
