What is a light year and explain it using a suitable example which talks about position of stars?
A light year, is the distance that you would travel in one year if you were traveling at light speed. It is equal to about 6 trillion miles and 9 trillion kilometers. It doesn't really deal with the position of the stars but their distances from earth. Example: Sirius is about 8 light years from earth. If you traveled at light speed in its direction, you would arrive in about 8 years.

Explain how polarized light is different from non-polarized light.?
In polarized light, the plane of the electrical (and magnetic) oscillations is the same for all photons (particles of light). For example, if the light is traveling away from you, all photons might have electrical oscillations that go up and down.
Is the position of the star as seen by us the true position?
No, the position of a star as seen from Earth is not the true position of the star in space. The light we see from stars is often from thousands or millions of years ago due to the vast distances they are located from us. Their current position may have changed since that light was emitted.
What is cool light?
The light which comes from Florescent tubes is called COOL LIGHT. Another example is L.E.D. lights as well. The light other than Halogen Lights is cool because Halogen Light is warm light.
Explain why aluminum can be found in the inner lining of airplanes?
It is light in weight and strong
Does red light promotes fern spore germination?
No, red light does not promote fern spore germination. Fern spores typically require moisture, suitable temperature, and suitable substrate for germination to occur. Light quality may have some effect on the process, but it is not a primary factor.
Explain why light coloured clothes are more suitable on hot days?
Because light coloured clothes reflects the heat off your body but dark coloured clothes absorbs the heat in.
Is the waterproof can light suitable for use in the shower?
Yes, the waterproof can light is suitable for use in the shower.
What is a suitable replacement for light molasses in a recipe?

Where is the rear position light on a Volvo s60?
The 'Position' Light on the Volvo S-60 is the rear tail-light
Explain how polarized light is different from non-polarized light.?
In polarized light, the plane of the electrical (and magnetic) oscillations is the same for all photons (particles of light). For example, if the light is traveling away from you, all photons might have electrical oscillations that go up and down.
How do you hang a swag light?
To hang a swag light, first find a suitable location with a nearby power outlet. Install a ceiling hook or bracket securely into the ceiling. Then, attach the swag light's chain or cord to the hook and plug it into the outlet. Adjust the height and position as needed for proper lighting.
Is the waterproof recessed light suitable for use in a shower?
Yes, a waterproof recessed light is suitable for use in a shower as it is designed to withstand moisture and water exposure.
What is a simple example of acceleration?
A simple example of acceleration is a car speeding up from a stationary position at a traffic light. As the driver presses the gas pedal, the car's speed increases, showing acceleration.
What is an example of artificial light?
An example of artificial light is a light bulb.
Is burning a match an example of potential energy?
No, burning a match is an example of chemical energy being converted into heat and light energy. Potential energy is energy stored in an object due to its position or state.
Give another example in everyday life to explain this binary concept?
The book is either open or closed The light is either on or off Your eyes are either open or closed
Is light is an example of matter?
No, light is not considered matter in the traditional sense. It consists of particles called photons, which are massless and do not have a fixed position in space. While light exhibits characteristics of both waves and particles, it is classified more as a form of energy rather than matter.
