Physical science semester 2 study guide

What is wavelength in waves PSCI.PS4.1

• lowest point in wave

• highest point in wave

• distance from resting point to lowest or highest point

• corresponding points on a wave measured in meters

What is a crest in waves

• lowest point in wave

• highest point in wave

• distance from resting point to lowest or highest point

• corresponding points on a wave

what is a wave

• disturbance that transfers energy through matter or space

• disturbance that transfers matter through space

• disturbance that transfers energy through matter only

• disturbance that transfers energy through space only

what is a transverse wave

what is a longitudinal wave

What is a trough in waves

• lowest point in wave

• highest point in wave

• distance from resting point to lowest or highest point

• corresponding points on a wave

what is diffraction

• an object causes a wave to change direction & bend around it through an opening

• waves are transmitted through a medium

• wave strikes an object and is absorbed

• 2+ waves are added together and increase in amplitude

what is refraction

• bending of waves caused by a change in speed as it passes through different mediums

• waves are transmitted through a medium

• 2+ waves are subtracted from each other and decrease in amplitude

• 2+ waves are added together and increase in amplitude

when a sound wave bounces off a wall what is it called

• refraction

• absorption

• reflection

• defraction

NGSS.MS-PS4-2

what is absorption

• an object causes a wave to change direction & bend around it through an opening

• waves are transmitted through a medium

• wave strikes an object and is absorbed

• bouncing back of a wave when it hits a medium
