Ray optics is based on the assumption that light travels in a straight line. Diffraction effects (observed when light propagates through small apertures/slits or around small obstacles) disprove this assumption. Yet the ray optics assumption is so commonly used in understanding location and several ...
A. change the direction of light travel B. gather materials to seatter light C. avoid the absorption of light D. grow bigger to stop light11. The last paragraph tells us that larger transparent animals A. move more slowly in deep water B. stay see-through even after death C. produce ...
A car travels in a straight line for 2.9 \ hr at a constant speed of 77 \ km/hr . What is its acceleration? (Answer in units of m/s^2) How many miles does light travel in 1 hour? The speed of light is 1.86 x 10^5 miles per s...

Light typically travel in a straight line. But som e materials slow a n d scatter (散射) light, bouncing it away from its original path. Others absorb light, stopping it d e a d in its tracks. Both scattering an d abs orption mak e an object look different from oth er objects aro...
When light travels through space from the sun, all of the frequencies of light travel in a straight line. When light hits the atmosphere, however, the photons begin to collide with gas molecules. Red, orange and yellow photons have long wavelengths and can travel right through the gas molecul...
Light waves appear to travel in straight lines since Athese are not absorbed by the atmosphere Bthese are reflected back by the atmosphere Ctheir wavelength is small Dtheir velocity is very largeSubmit Light after being a wave motion, appears to travel in straight line because AVelocity of ...
