TRANSPARENT, TRANSLUCENT AND OPAQUE
Q1) what are transparent objects?
Q2) What are translucent objects?
Q3) What is opaque?
Q4) What is the difference between transparent, translucent and opaque objects?
Answer Key
Q1) what are transparent objects?
A transparent object is an object in which light can easily pass our call transparent object for example glass clear water are examples of transparent objects.
Q2) What are translucent objects?
A translucent object is an object in which the portion of light passes but major portions cannot be seen are called translucent objects for example tracing paper filter paper.
Q3) What is opaque?
An opaque object is the object in which the light cannot pass through what we call opaque objects, for example book wood.
Q4) What is the difference between transparent, translucent and opaque objects?
A difference between translucent transparent and opaque objects is that in transparent objects light can easily pass through in translucent objects little portion of light is visible whereas in opaque objects the light doesn’t pass through this particular type of object.
PROPERTIES OF LIGHT
Q1) What are the properties of light?
Q2) Explain how light travels in a straight line?
Q3) How shadow is formed?
Q4) what are eclipses?
Q5) What is a solar eclipse?
Q6) What happens in a solar eclipse?
Q7) What is lunar eclipse?
Answer Key
Q1) What are the properties of light?
Ans light travels in a straight line secondly lights forms shadows and d shadows of opaque objects formed due to light lastly the property of light is the formation of eclipse.
Q2) Explain how light travels in a straight line?
Ans light travels in a straight line because when we sit in front of a luminous object then light imitates from it and enters our eyes in this manner you can see the luminous object. In case we place a book or cardboard in front of our eyes then we cannot see the visibility of light.
Q3) How shadow is formed?
Ans light travels in a straight line in all directions but when an opaque object becomes an obstacle to that part of light it makes darkness behind it in the region where the rays of the light cannot reach like this way the shadows are formed.
Q4) what are eclipses?
Ans Earth and moon form shadows on each other. Shadow of moon and earth formed in this manner are called at eclipse
Q5) What is a solar eclipse?
Ans The formation of the shadow of the moon on earth and the appearance of the sun as dark is called a solar eclipse.
Q6) What happens in a solar eclipse?
A Solar eclipse moon passes between earth and sun.
Q7) What is lunar eclipse?
And Earth passess between the sun and the moon.
PINHOLE CAMERA
Q1) What is a pinhole camera?
Q2) How was the pinhole camera made?
q3) what is crescent?
Q4) When does the moon appear as full?
Q5) What are the phases of the moon?
Q6) What is the new moon?
Q7) When does the moon look like a bright crescent?
Q8) When does the moon appear half bright?
Q9) How many phases of the moon are there?
Answer key
Q1) What is a pinhole camera?
A Pinhole camera is very useful to see and observe that light travels in a straight line.
Q2) How was the pinhole camera made?
As a pinhole camera we simply need a box whose inner box walls are completely dark. There is a small hole on its one side and a screen plate is fixed on the opposite side of the hole so when a pinhole camera is brought in front of an object the light coming from the object enters this whole and forms an inverted image on the screen.
q3) what is crescent?
And the moon fast at night is brown and thin in colour and is called Crescent.
Q4) When does the moon appear as full?
Ans On 14th night the moon appears as full.
Q5) What are the phases of the moon?
ans he continuously changing appearance of moon are called phases of moon
Q6) What is the new moon?
ans the portion of moon in front of earth is very dark for this reason it does not appear to us so this phase of moon is called new moon
Q7) When does the moon look like a bright crescent?
Ans in a situation when sunlight reaches out after partial reflection from the right side of the moon and for this case the moon looks like a bright Crescent.
Q8) When does the moon appear half bright?
When sunlight reaches after reflection from half of the moon does the moon appear half bright.
Q9) How many phases of the moon are there?
Ans There are 8 phases of moon
