It affects neither the speed nor the wavelength.
absorption
diffraction
reflection
refraction
interference
A wave is diffracted as it passes through an opening in a barrier. The amount of diffraction that the wave undergoes depends on both the
amplitude and frequency of the incident wave
wavelength and speed of the incident wave
wavelength of the incident wave and the size of the opening
amplitude of the incident wave and the size of the opening
Which diagram best represents the shape and direction of a series of wave fronts after they have passed through a small opening in a barrier?
Why does white light from the sun form a colorful rainbow when it passes through water droplets in the atmosphere?
The droplets of water in the air have different densities
White light diffracts when it encounters water
The colors that make up white light refract at different angles
Different-sized water droplets refract white light at different angles
T/F: When sound waves move from one medium into another, their speed changes
True
False
Why do you not see an image when light reflects off a rough surface?
because not enough light is not reflected
because the reflection is specular
because the reflection is diffuse
because the law of reflection does not apply
What happens to the image when you move the candle to the focal point F1?
Get smaller and moves toward the lens
Get bigger and moves toward the lens
Get smaller and moves away from the lens
Get bigger and moves away from the lens
No image will appear
