- Q1
An echo is an example of sound wave
interference
diffraction
reflection
refraction
30s - Q2
Refraction occurs when a wave changes its
frequency
color
intensity
speed
30s - Q3
When considering light moving through a diffraction grating, you should treat the light as
neither a particle nor a wave
both a particle and a wave.
a particle
a wave
30s - Q4
A magnifying glass or hand lens is a bi-convex lens. It is convex on both sides, meaning that the glass is curved outward to form a dome. Things look bigger looking through convex lenses. When light passes through the lens, it is bent or _______.
reflected
refracted
conducted
absorbed
30s - Q5
The beam of a light spreads out after leaving the flashlight. The beam grows wider and wider. This is best explained by
diffraction
reflection
interference
refraction
30s - Q6
A student is given an assignment to demonstrate diffraction. He takes a photograph of a straw in a glass of water. The straw appears bent at the water level. Which best describes this example?
This is an example of dispersion and not diffraction
This is a good example of diffraction
This is an example of refraction and not diffraction
This is an example of reflection and not diffraction.
30s - Q7
When sunlight strikes oil on the surface of water, a variety of colors are observed. What is the best explanation for this observation?
Oil reflects the light and the lens of our eyes break it into component colors.
The visible spectra of white light travel at different speeds. reaching the oil separately so we see the component colors
The components of white lights are refracted at different angles due to their various wavelengths.
Oil has a very high index of refraction, trapping and reflecting the visible spectrum.
