15 Questions
According to Huygens' principle, what are the wavelets formed by drawing a half-circle around each point on a wave?
Half circles
What happens when waves interfere constructively?
The waves combine into one wave with a larger amplitude
What is the term used to describe the pattern that occurs when light waves diffract and interfere with each other?
Interference pattern
According to Huygens' Principle, how can you predict a wave's position in the future?
By analyzing its current position
What did 19th-century physicists believe about light?
It is a particle
What did Christian Huygens contribute to the understanding of light?
He developed Huygens' Principle
Which type of interference occurs when waves are shifted by exactly half a wavelength?
Destructive interference
What is the equation for calculating the path difference in a single slit experiment?
Path difference = distance between the center of each slit * sine(angle)
What is the relationship between intensity and amplitude for light waves?
Intensity is directly proportional to the square of the amplitude
According to the text, what happens to the rays passing through the middle third and bottom third of the slit?
They cancel each other out
What causes the bright line in the shadow of the coin?
Both diffraction and interference
What creates the little ripples spreading outward from the circular shadow?
Both diffraction and interference
What happens when diffracted waves run into each other?
They combine to form one wave with a higher amplitude
What do the crests and troughs of different light waves do when they combine?
They form one wave with a higher amplitude
What did the text discuss in addition to the double-slit experiment?
The diffraction pattern from a single slit
