1.What is the speed of light 300,000,000 ms answer
2.What is the law of reflection? “The angle of incidence = the angle of reflection” answer
3. What is a “normal” line answer A dotted line drawn at right angles to a surface
4. What is meant by the term refraction answer Refraction is when light slows down as it passes from air into glass. This can cause it to change direction.
5. What happens if light passes from air into glass at an angle to the normal? It slows down and bends towards the normal. answer
6. What is meant by the term “critical angle” The angle above which light in glass is not refracted out but is totally internally reflected answer
7. What type of lens brings parallel rays of light to a a focus point? A convex or converging lens answer
8. What does a prism do to a ray of white light? Splits it into a visible spectrum. answer
9.What is the name of the family of waves that all travel at the speed of light? The Electromagnetic Spectrum answer
10.What is the order of the sections in the EM spectrum starting with the lowest frequency? Radio &TV, microwaves, Infrared, Visible, Ultra Violet, X-Rays, Gamma Rays answer
11. Name a detector used to detect Infrared radiation. Thermal imaging sensor or photodiode or skin. answer
12. Which section of the EM spectrum has the highest energy ? Gamma rays Gamma rays answer
13. Are light waves transverse or longitudinal? Transverse answer
14. What kind of light is used to send information through a fibre optic cable ? Laser light Laser light answer
15. What type of lens would correct the vision of a short sighted person A concave or diverging lens. answer
16. What is the wavelength of a radio wave that has a frequency of MHz ? wavelength = v/f = 300,000,000 / 102,500,000 = 2.93m answer
Electromagnetic waves- transverse waves consisting of changing electric and magnetic fields Carry ENERGY from place to place Different from mechanical.

Electromagnetic Waves and Light. Electromagnetic Waves Electromagnetic waves do not require a medium to travel. They are created by oscillating (moving)
True or False? 20 questions. Question 1 Sound is a transverse wave False its longitudinal!
Refraction and Lenses AP Physics B. Refraction Refraction is based on the idea that LIGHT is passing through one MEDIUM into another. The question is,
The electro-magnetic spectrum. Key facts All the waves travel at the same speed – around km/s.
By Will B. Electromagnetic waves The different waves that make up the electromagnetic spectrum are as follows in order of increasing frequency; Radio.

An Introduction to Refraction SNC2D. Index of Refraction Light will travel more slowly in more dense materials. The ratio of the speed of light in a vacuum.
Properties of Light. ELECTROMAGNETIC WAVES Light is an example of an electromagnetic wave. It requires no medium through which to travel.
Light Chapter 4. What is Light? There are two different ways of talking about light: There is the "particle" theory, expressed in part by the word photon.
© Boardworks Ltd 2003 Lenses. © Boardworks Ltd (c) Thin converging lens Core Describe the action of a thin converging lens on a beam of light.
Waves Energy is sometimes transferred from place to place by traveling in waves. Sound and light travel in waves. Some substances transport energy through.
Refraction of Light. Review: Reflection Law of Reflection The angle of incidence equals the angle of reflection The incident and reflected rays lie in.
P1.5 The use of waves P1.5 The use of waves for communication and to provide evidence that the universe is expanding Electromagnetic radiations travel.
Waves and Energy Physics, Grade 8. Types of Waves Mechanical Waves need matter (medium) to travel through Mechanical Waves need matter (medium) to travel.
The Speed & Nature of light. What is light? Light is a form of electromagnetic radiation. Light is made up of waves of tiny bundles of energy call photons.
Waves and the Electromagnetic Spectrum Ch. 17. What is an electromagnetic wave? A transverse wave A wave that consists of vibrating electric and magnetic.

Fundamentals of Light. Light Light is not only comprised of the light we can see (visible light), but also other types of light waves, called EM waves.
Rainbows. Waves The white light spectrum 1.White light is a mixture of different colours of light. 2.Newton used a glass prism to separate the colours.
