Appreciation Of the poem Upon Westminster Bridge

 

Appreciation Of the poem Upon Westminster Bridge

‘Upon Westminster Bridge’ is a Petrarchan sonnet written by the renowned Nature poet William Wordsworth. It is a 14-line poem divided into an octave and a sestet. The poem is about the poet’s feelings of fascination and wonder as he watches the early morning in the city of London from the Westminster Bridge.

The poet has used poetic devices such as Hyperbole, Personification, Alliteration, Metaphor and Simile. The use of Simile –‘This city now doth, like a garment, Wear the beauty of the morning’ creates a picturesque image. The artistic use of end-rhymes gives a song-like rhythm to the poem. The rhyme scheme is Ababa cdcdcd.

The main message of the poem is the beauty of the city in its natural setting before the routine activities have begun. This highlights the negative impact of industrialization which the poet believes may ruin the city. Overall, the poem is brilliantly outstanding and allows the readers to visualize the picture painted by Wordsworth. The tone of the poem changes from overwhelmed to calm, to excited and amazed by the end. The poet’s calling out to God in sheer amazement is indeed a sublime finish to the beautiful sonnet. This poem validates the fact that Wordsworth was a true Nature poet.

I like this poem for its simplicity, freshness & picturesque depiction. This over 200 year’s old poem has the supreme power to take anyone close to nature.

Appreciation of the poem – ‘There is another sky’

 

Appreciation of the poem – ‘There is another sky’

The poem ‘There is another sky’ is written by Emily Dickinson. Emily Dickinson is America’s one of the greatest and most original poets of all time. ‘There is another sky’ is an inspirational poem. It is a Petrarchan sonnet of fourteen lines consisting of two stanzas – an octave of eight lines and a sestet of six lines. Through this poem, the poet addresses her younger brother, Austin, and urges him to return home. Home is depicted here as a world, a garden, an ideal place.

The first stanza tells about the ‘other’ place and in the second stanza the poet urges her brother to return to this place. The poem emphasizes the serenity, peace and happiness surrounding one’s home. At the centre of the poem is the special sibling bond.

The theme of the poem is that happiness and gloom are the two sides of life and each one has to focus on what one desires. The lines of the poem are short and the language is simple. The poet has used inversion, hyperbole, onomatopoeia and alliteration. The poem is philosophical in nature and the tone of the poem is encouraging and pleading.

The message of the poem is that one should not get affected by trials and tribulations of life. I like this poem for its universal appeal. Anybody can relate to the genuine emotions and feelings involved in this poem. The poem is like a call of return to one’s sibling who are profoundly missed.

Appreciation of the poem (cherry tree)

 Appreciation of the poem (cherry tree)

Cherry Tree is a beautiful poem written by Ruskin Bond. It is a narrative poem describing the everyday struggle of a plant to grow & blossom. The poet’s tone is optimistic, full of wonder for the nature – he focuses on the growing aspect of nature. The poem has a beginning, middle and an end. It’s a simple poem about the poet’s innocent & pure joy. All the incidents are in nice sequence.

The poet planted a cherry seed which grew into a full blossomed tree after a wait of eight years. The poem is all about this wonderful experience and survival instinct of the tree. The time, that is the seasons and the rain helped the tree grow and the poet watched this patiently without much to do. The poem is about the poet’s sense of achievement & pride of having nurtured a tree.

The style & language of the poem is simple. Poetic devices such as Alliteration, Antithesis, Climax, Personification are used by the poet. The important aspect of this poem is its picturesque depiction & colourfull imagery. The whole process of a seed turning into a plant is been made appealing to the readers with colourfull & vivid description. The references of seasons, the sky, animals, birds, insects focus on the wonders of nature.

The poem gives a message of nature conservation- tree plantation & its importance. The cherry tree is indeed a ‘Giving Tree’. It also speaks about the tree’s determination to grow despite all odds.

I like the poem for its positive, optimistic tone. It encourages us to overcome the obstacles, hardships we may face in life & become resilient like the cherry tree.

At mean position,kinetic energy will be maximum and potential energy will be minimum

A3.

A simple pendulum whose period is two seconds is called a second's pendulum.

A4.

The epoch in simple harmonic motion (SHM) is the phase of a vibrating particle at the start of its motion, or when time t = 0. It's also known as the initial phase. 

A5.

The time period of a (SHM) remains the same if its amplitude is doubled. This is because the period of an SHM depends on inertia and spring factors, which are independent of amplitude. 

A5.

Force constant is the force required to produce a unit extension or compression in a spring. It's also known as the spring constant and is represented by the symbol k. The SI unit for force constant is newtons per meter (N/m).

A6.

3/4th 

A7.

given V = 0.24 m/s ,  a = 0.48 m/s2 to find time period T

formula : T = 2*pi*V /a

T = 2*3.14*0.24 /0.48 = 3.14 seconds

Time period T = 3.14 seconds

A8.

given T = 1/8 seconds , to find frequency F

formula :  F = 1/T 

F = 1/1/8 = 8 hertz
