Consists of changing electric and magnetic feilds.
What is an electromagnetic wave
100
a copy of an object.
What is image
100
combinations of transverse and longitudinal waves.
What is surface waves
100

What is concave mirror
200
classified according to how they move.

What is newtons second law.
500
shows a region of different temperatures in different colors.
What is thermogram
500
occurs when parallel rays of light hit a smooth suface.
What is regular reflection
500
the angle between the reflected wave and the imaginary line.
What is the angle refelection
500
the force of gravity acts between all objects in the universe
What is the law of universal gravitation
500
when force is applied to a confined fluid, an increase in pressure is transmitted equally to all parts of the fluid.
