• waves that are useful to seismologist in their study of the layers of the earth
• waves that are useful to seismologist in their study of the layers of the earth

  Body waves
• Body waves


  • Useful to seismologists in their study of the layers of the Earth
• Using the triangulation method to locate the epicenter of the recent earthquake


  1. Obtain data from three different seismological stations

  2. Determine the difference in the arrival time of S and P waves recorded from each of the seismological stations

  3. Determine the distance of the epicenter from the station

  4. Use the triangulation method to locate the center
• Transform fault boundaries


  Past each other without diverging or grinding
• Transform boundaries


  Tend to be cooler than convergent boundaries that's why volcanoes rarely form along transform boundaries
• Lens


  An optical instrument that is a curved piece of glass that is used to refract light
• The size of the image formed by a concave lens and a convex mirror is reduced
• Filament in an automobile headlight


  Radiates light that is reflected from a converging mirror at the principal focus where the filament should be placed for the reflected rays to form a parallel beam of light
• Diffuse reflection


  Occurs when parallel light rays hit and bounce on a rough or bumpy surface
• Clock with no numbers in front of a plane mirror


  The time indicated in its image is 9:30 when the real time is 2:30
• The minimum size of the plane mirror that a 1.4 m tall man needs to see his full self is 0.7 m
• An object is located 20 cm in front of a concave mirror whose radius of curvature is 20 cm. The image formed is real, inverted, and same size as the object
• EM waves


  • All EM waves have the same speed
  • All EM waves travel at the speed of light
  • As the frequency of the wave increases, the energy of the wave also increases
  • As the wavelength decreases, the frequency of the wave increases
• Infrared and Ultraviolet Ray


  Lie at the ends of the visible spectrum
• 1. rays


  • Type of electromagnetic wave is used in diagnosis of bone fractures
  • Electromagnetic wave is not used in telecommunications
• Microwave


  Type of electromagnetic wave is used in RADAR
• Ultraviolet ray


  Type of electromagnetic wave used in checking bankbook signature
• Specular reflection


  Happens when parallel light rays hit and bounce on a smooth surface
• Camera is an optical instrument that works like a human eye
• Specular reflection of light is why your face is clearly seen when looking at a pool of still water
• Convex mirrors produce a wide-field view compared to plane mirrors, which is why some department stores and convenient stores place them in each corner above the ceiling
• It will be easy for the drivers of the vehicles to read it in their side mirrors because the mirror reverses its image
• Motor


  Converts electrical energy to mechanical energy
• If the amount of food or resources available increases


  The carrying capacity for an animal will increase
• Higher biodiversity, higher stability
• According to Lamarck's Theory of use and disuse, the body structures develop because they are used extensively
• Hemoglobin is a protein in red blood cell that transport water from the lungs to the body cell does NOT describe the importance of proteins in the body
• Receptor --- Sensory Neuron --- Brain --- Motor --- Effector is the correct body processes through the nervous system
• In response to elevated body temperature

  Your blood vessels dilate, and you begin to sweat to indirectly maintain homeostasis
• We sometimes tend to yawn when we see someone yawn because of Brain and spinal cord
• Ovulation is positive feedback
• Menstrual periods are irregular and can be late for up to 10 days more doesn't happen during ovulation
