when is one term in a sequence bigger than the next term in the sequence??

will the cat catch the mouse? No, not according to the rules of the game

how many people are lying?

how can we find dates that don’t have any repeating numbers?

lets do some stuff with inequalities and trig functions because we hate fun

Recall Questions What is a photon?? A quantum of energy of electromagnetic radiation. What is the photoelectric effect?? The emission of electrons from a metal surface when illuminated with light. What is a photoelectron? An electron that has been removed from a metal by absorbing a photon. What is the work function?? The minimum energy required to release an electron from the surface of a metal. What is the threshold frequency?? The minimum frequency of light required to produce photoelectrons from a metal.

Recall Questions State what is meant by the superposition principle?? When two or more waves meet at a point, the resultant displacement is the vector sum of the displacements of the individual waves. State what is meant by coherent waves?? Waves that have a constant phase difference. State the conditions for two waves to be coherent?? The waves must be of the same type and have the same frequency. State what is meant by interference?? The superposition of waves from coherent sources.
