A

How loud or quiet a sound is , in decibels dB

32
Q

Pitch

A

How high or low a sound is

33
Q

Incident ray

A

Incoming ray

34
Q

Reflected ray

A

Outgoing ray

35
Q

Angle of reflection is

A

Between the normal and reflected ray

36
Q

Angle of incidence is

A

Between the normal and incident ray

37

A

SIDOT

44
Q

Electromagnetic spectrum

A

The range of all types of EM radiation

45
Q

Ionising radiation

A

A form of energy that acts by removing electrons from atoms and molecules of materials that include air , water and living tissue

46
Q

Visible light

A

The segment of the electromagnetic spectrum that the human eye can view

47
Q

Reflection

A
48
Q

3 similarities between water and light waves

A
  1. Both transverse waves
  2. Transfer energy from one place to another
  3. Can be reflected
49
Q

Which two parts of the eye help you to focus on an object?

A

Lens and cornea

50
Q

How do digital cameras form images?

A

Light causes the sensor to generate an electrical charge. The changes in charge are read by a computer and turned into an image

51
Q

What can ultrasound be used for?

A

To clean things
Physiotherapy

52
Q

How do microphones work?

A

The vibrations in a sound wave make a sensitive diaphragm vibrate inside a microphone. The microphone converts the vibrations to electrical signals

53
Q

Wave-speed equation

A

Wave-speed( m/s ) = distance ( m ) divided by time ( s )

54
Q

How does frequency affect the pitch of a wave?

A

Sound waves with high frequency produce high pitched sounds and sound waves with low frequency produce low pitched sounds

55
Q

How does amplitude affect the loudness of a wave?

A

The higher the amplitude , the louder the sound and the lower the amplitude the quieter the sound is

56
Q

Order of electromagnetic spectrum

A
  1. Radio waves
  2. Microwaves
  3. Infrared light
  4. Visible light
  5. Ultraviolet light
  6. X rays
